She is a woman of great knowledge, much can be learned.A. in whomB. about whomC. of whomD

She is a woman of great knowledge, much can be learned.
A. in whom
B. about whom
C. of whom
D. from whom

A. in whomB. about whomC. of whom(答案→)D. from whom解析：考查定语从句中的;介词+which/whom引导的定语从句，因为先行词是knowledge，所以用which，又因为定语从句中的动词是learn，应该和from搭配，所以选D，句意是：她是知识渊博的女性，有很多可以学习的东西。选D。
