问题 ______their help, he could not have finished the task on time.

选项 A、Had not it been for
B、It hadn’t been for
C、Had it not been for
D、Hadn’t been for

答案 C

解析该题是语法结构题，考查虚拟语气在If it(be) not for…句型中的用法。该句型的意思是“要不是”，相当于but for和without，如：If it were not for the leadership of the Party．we could not be living a happy life today．要不是有了党的领导，我们今天就不可能过上幸福生活。在该题中，虚拟语气用来表示与过去事实相反，从句中的if被省略，出现倒装语序，第一个助动词要提到主语前面，但是不能把否定助动词not一起提前。因此，根据题意和语法规则，选项C为最佳答案。
