Do you know who lives in the building   （）       there is a well.

题目解析 题目：Do you know who lives in the building （） there is a well. 选项：A. in front of it B. in front of whose C. in front of which D. in the front of which 答案：C 解析：这又是一个定语从句的填空题。句子中含有"the building"，需要填入一个关系代词作为连接词。关系代词在这里充当宾格形式，指代前面的"the building"，应该是"in front of which"，意为"在其前面"。其他选项不符合句意。
