The consumer’s optimum occurs where the budget line is tangent to the highest attainable indifference curve — i.e., where the marginal rate of substitution (MRS) equals the price ratio. At point E the consumer is on the budget line but not at that tangency: the indifference curve through E lies below a higher indifference curve that the budget line intersects further up and to the left.

Relevant concepts:
- Indifference curves show combinations of x and y giving equal utility; higher curves = higher utility.
- The budget line shows feasible combinations given prices and income; its slope equals −(px/py).
- Utility maximisation requires choosing the feasible bundle where an indifference curve is tangent to the budget line (MRS = px/py).

Step-by-step reasoning:
1. Identify feasibility: E lies on the highest budget line (consumer spends all income) but E is not at a tangency with a higher indifference curve.
2. Move along the budget line from E toward the left and up: this means consuming less x and more y while keeping expenditure constant.
3. As we move left-up along the budget line we reach an indifference curve that lies above the one through E (higher utility). This movement continues until the indifference curve becomes tangent to the budget line (the tangency point is the interior optimum).
4. At E the slope of the indifference curve relative to the budget line indicates the consumer is willing to trade x for y (i.e., they value additional y relatively more), so shifting expenditure from x to y raises utility.

Why the correct option is correct:
- Consuming more y and less x moves the consumer to a higher indifference curve while staying on the same budget line, increasing utility until tangency is reached.

Why other options are wrong:
- b (less y, more x) moves to a lower indifference curve (lower utility).
- c (more of both) is infeasible on the same budget.
- d (no change) leaves utility below the attainable maximum.

Thus the correct action is to consume more y and less x, matching the provided answer.
