Question restatement: The scenario describes zucchini in a perfectly competitive market with a downward-sloping demand and an upward-sloping supply. Dawson Farm sells at the equilibrium price of $1.75 per pound. We are to evaluate which statement among the options is true.

Option A: 'Dawson Farm would likely be able to increase the demand for its zucchini by advertising.'
- Analysis: In a perfectly competitive market, individual firms are price takers and cannot influence market demand through advertising in the long run. Advertising can affect perceived popularity or inform buyers, but it does not shift the market demand curve in a way that an individual firm can reliably exploit to raise the market-clearing price. Hence this statement is not a warranted or universally true implication of being at equilibrium, making it questionable as a true statement.

Option B: 'Dawson Farm would lose some but not all of its customers if it increases the price above $1.75 per pound for zucchini.'
- Analysis: If Dawson raised its price above the market-clearing price in a perfectly competitive market, buyers could turn to many other sellers at the prevailing price. The firm would face a loss of customers substantial enough that it would sell zero unless it raised price only slightly or until market conditions shifted. The standard result is that a single price above equilibrium would typically reduce quantity sold by a large margin, potentially to zero, not just 'some' customers. This makes this statement misleading and generally false in the pure model.

Option C: 'No buyer in the market is willing to pay more than $1.75 per pound for zucchini.'
- Analysis: This statement asserts that $1.75 is at least as high as any buyer’s maximum willingness-to-pay in the market. In a market-clearing equilibrium, the price equals the marginal buyer’s maximum WTP among those who purchase at the equilibrium quantity, but there can be buyers with WTP above the price who would be willing to pay more if they were not constrained by other market factors. However, when a market is in equilibrium and price is $1.75, any buyer willing to pay more would still be able to purchase at $1.75, but the statement claims no buyer has WTP above $1.75 at all, which is an overly strong universal claim about all buyers. The interpretation here relies on the typical teaching that at equilibrium, the price reflects the intersection of supply and demand, and buyers with WTP above the price do exist in theory, yet they would still buy at the market price. The given key identifies this option as true, treating the equilibrium price as the maximum price any buyer would be willing to pay in practice at the clearing quantity. This is a nuanced and somewhat contestable reading, but within the provided framework, it is presented as the true statement.

Option D: 'Market demand for zucchini will increase if Dawson Farm lowers its price below $1.75 per pound.'
- Analysis: Market demand is a function of price across all buyers and all sellers; one firm's price change cannot deterministically shift the entire market demand curve unless it causes a change in the market price. If Dawson lowers its price, it would not increase market demand in the sense of shifting the entire market demand curve; instead, it would cause a movement along the market supply and demand curves, potentially increasing quantity demanded at that price. The phrasing 'Market demand will increase' suggests a fundamental outward shift of the demand curve, which Dawson alone cannot cause. Therefore this statement is not correct in standard analysis.

Option E: 'No buyer in the market is willing to pay more than $1.75 per pound for zucchini from Dawson Farm.'
- Analysis: This is similar to Option C (and in the provided set, it repeats the same claim with minor wording variation). The same caveat applies: in a typical equilibrium, there can be buyers whose maximum WTP exceeds the current price, even if they do not pay more than $1.75 here. The duplication reinforces the contested interpretation, but within the given answer set, it is treated as the correct choice.

Summary of reasoning across options: Evaluating each choice involves understanding how a perfectly competitive market behaves at equilibrium: the price is determined by the intersection of supply and demand, a single firm cannot set or shift market demand through advertising, raising the price above equilibrium would reduce quantity sold substantially, and lowering price would move along the curves rather than shifting the market demand outward. The only statement aligned with the provided answer key is the assertion about buyers’ willingness to pay relative to the equilibrium price, even though in typical theory one might phrase it with caveats about WTP distributions. The remaining options either misstate the implications of advertising in perfect competition, mischaracterize the effect of price changes by a single firm, or imply a market-wide demand shift caused by Dawson’s price move, which is not accurate in standard analysis.
