问题 The law of diminishing marginal utility______.

选项 A、suggests that total utility will eventually decrease if enough of the good is consumed
B、suggests that as a consumer buys more of a good, its price will drop
C、provides an explanation for perfectly elastic demand curves
D、suggests that as a individual’s consumption of a good increases, his marginal utility must eventually decrease

答案D

解析 答案为D项。the law of diminishing marginal utility“边际效用递减规律”。该规律认为在保持消费者的效用水平不变的前提下,随着一种商品消费数量的增加,消费者每增加一单位该商品消费所获得的效用增加量逐渐减少。故本题选D项。
