Correct answer is A

MUx/Px = MUy/Py, where MUx is the marginal utility derived from good x, Px is the price of good x, MUy is the marginal utility of good y and Py is the price of good y. A consumer should spend his limited money income on the goods which give him the most marginal utility per dollar. Only when the ratio of MU/P is equal for all goods is a consumer maximizing his total utility.
