The condition required for a consumer to be maximizing utility for any pair of products X and Y is that the marginal utility per dollar spent on X (MU_X/P_X) is equal to the marginal utility per dollar spent on Y (MU_Y/P_Y). This means that the consumer is allocating their budget in such a way that the last dollar spent on both X and Y provides the same marginal utility. Option C represents this condition. Option A is incorrect because it uses the budget constraint in the equation, which is not necessary for maximizing utility. Option B is incorrect because it only represents the equation for equalizing marginal utilities, but it does not take into account the prices of the products. Option D is incorrect because it flips the marginal utility and price terms, which is not correct. Option E is incorrect because it only represents the budget constraint and does not take into account the marginal utility.
