Question restatement: Which of the following statements is correct?

Options:
1) If demand increases, then price will decrease.
2) If demand decreases, then price will decrease.
3) If price increases, then demand will decrease.
4) If price decreases, then demand will decrease.

Analysis of each option:
Option 1: If demand increases, then price will decrease.
- This statement confuses the direction of the relationship between demand and price. When demand increases (a shift of the demand curve to the right), the equilibrium price tends to rise, not fall, assuming supply remains constant. While the exact price movement depends on the supply response, the typical outcome is a higher price. Therefore this option is generally incorrect.

Option 2: If demand decreases, then price will decrease.
- Here, a decrease in demand (a leftward shift of the demand curve) leads to a lower equilibrium price if supply is unchanged, since buyers are willing to pay less at every price. This aligns with the basic supply and demand framework, making this option a correct description of the typical outcome in a competitive market under ceteris paribus conditions.

Option 3: If price increases, then demand will decrease.
- This statement uses the term 'demand' where the correct concept is 'quantity demanded.' Price changes cause a movement along the demand curve (changing quantity demanded), not a decrease in the entire demand curve. The law of demand says price rises lead to a smaller quantity demanded, not a reduction in overall demand. Hence this option is technically incorrect due to imprecise terminology.

Option 4: If price decreases, then demand will decrease.
- This is opposite to the usual effect. A price decrease typically leads to an increase in quantity demanded, holding other factors constant, not a decrease in demand. So this option is incorrect.

Summary of reasoning:
- Option 1 misstates the direction of price change when demand shifts and confuses curve movement with price level.
- Option 2 correctly reflects that a decrease in demand tends to reduce the equilibrium price (under ceteris paribus).
- Option 3 incorrectly uses 'demand' instead of the more precise 'quantity demanded' and mischaracterizes the relationship.
- Option 4 contradicts the standard effect of a price drop on quantity demanded.
