问题 The______choice for a consumer, therefore, is the choice among the available ones that will enable him or her to maximize utility.
选项 A、optimal
B、optional
C、optical
D、optimistic
答案A
解析 句子大意为：消费者拥有的最佳选择自由就是可以使效用最大化的选择自由。在给出的选项中：optimal“最佳的”，仔细体会可以发现，该词符合题干语义；optional“可选择的”，该词没有A项切题；optical“光学的”；optimistic“乐观的”。本题考查常见短语动词搭配。所以，正确答案是A。
