问题描述：
my parents live in a tall building,and its window faces to the blue sea
and its window根据什么来选呢
A its window B and its window Cand the window of which D the window of it
答
哎？答案是B吗？
我觉得应该是C哦，因为building后有一个逗号，说明这个句子没说完，后边应该加一个非限定定语从句。
the window of which中的which指代前面的building
如果用and，前面不会用逗号的，你再去问问你的老师确认一下好了。
答
选B!
一定是B,我做过的.
如果是C,根本说不通,是C的话,不能要[of]
