It is in the room__ my father was born in 1932__ I was bornA.where,thatB.that,whenC.that,whereD.where,whenwhy choose A

A
本句是强调句，去掉强调的成分，句子是
I was born in the room where my father was born in 1932.
翻译：我出生的地方正是我父亲在1932年出生时候的那件房间。

where my father was born in 1932,此状语从句是用来修饰in the room的，where在这里充当状语的成分（即in the room），如果将该句还原，那就是My father was born in the room in 1932，很明显where 充当的是状语的成份。后面一个that 这是强调句型的结构：It is ...that ...句型！译为：我父亲1932年出生时的那房间正是我出生的房间！

先是表语从句，It is...that强调句型！

第一个where是引导定语从句my father was born in 1932
第二个that是强调句结构 it is+被强调部分+that

it is in the room that i was born.是一个强调句,句型为It .that
where my father was born in 1932 是定语从句,是对the room 的修饰

首先:It is ……that……构成了强调句型。
强调的是地点状语从句。
