Question

.the house I grew up () has been taken down and replace by an office building .

A.in it B.in C.in that D.in which 为什么选B?

Answer 1

分解成两句就好理解了
the house has been taken down and replaced by an office building
I grew up in the house
两句合并成一句，以第二句修饰第一句中的the house，就知道是选B了

应该没有省略where，因为where是副词，不可能前面有介词，如果说省略的话，应该是省略which
in which=where

Answer 2

其实是有省略where，完整的是the house where I grew up in。这一整句作为主语。

追问

为什么省略WHERE?

Answer 3

I grew up in the house.这是习惯说法
