(单选题)

The factory was built in a secret place, around ______ high mountains.

A.which was

B.it was

C.which were

D.them were

参考答案：C

参考解析：

考查关系代词which的用法和主谓一致其他。句意：工厂建在一个秘密的地方，周围是高山。此处around ______ high mountains为定语从句，修饰前面的先行词place，先行词在定语从句中充当around的宾语，所以用which；在定语从句中，地点状语置于句首，谓语动词的单复数由后面的名词的单复数形式决定，因此此处应使用were。故选C。
