________ Anirban  Maitra, a professor at Oxford University, Jack’s success would not have been possible.

A．If it weren’t for	B．Were it not for
C．Had it not been for	D．If it hasn’t been for

答案

C

解析

试题分析:考查虚拟语气。从主句would not have been推断句子应该是对过去情况的虚拟假设，所以从句应该用had done，故C选项正确。句意：要不是牛津大学的教授--- Anirban Maitra, 杰克是不可能成功的。
