(单选题)

American women usually identify their best friend as someone ______ they can talk frequently.

A.who

B.as

C.about which

D.with whom

参考答案：D

参考解析：

考查介词+关系代词的用法。句意：美国女人通常把最好的朋友看作是一个经常与之交谈的人。_______ they can talk frequently是限制性定语从句，修饰先行词someone。talk为不及物动词，后接宾语时需要加介词，talk with意为与……交谈，talk about意为谈论。根据句意可知，此处应用介词with，构成介词+关系代词引导定语从句的形式。故选D。
