She’s __what_ is known as a nosy person — she is always dying to know what’s going on in other's lives.

She’s _________ is known as a nosy person — she is always dying to know what’s going on in
other's lives
A what B who C which D that
选A
因为what= the thing which/ that .
She is后面需要【表语】， is known的前面需要【主语】。所以选what。

what引导的从句是宾语从句
what在从句中充当主语
what=the + 名词 + that （名词根据句意而变,本句意为the person that)
who引导名词从句是“谁”的意思.
如果要先B,
改为
the person who is known as ...就对了.
She is the person who is known as a nosy person...
又如：
This place is what is called Mount Tai.（这地方就是被叫做泰山的地方.what=the place that)
