Suppose that each week Henry buys 12 peaches and 3 apples at his local farmer's market. Both kinds of fruit cost $1 each. From this we can infer that:
选项：

A:if Henry is maximizing his utility, then his marginal utility from the 12th peach he buys must equal his marginal utility from the 3rd apple he buys.;
B:for Henry the law of diminishing marginal utility does not apply to peaches.;
C:if Henry is maximizing his utility, then his marginal utility from the 12th peach he buys must be greater than his marginal utility from the 3rd apple he buys.;
D:Henry is not maximizing his utility.
