The place 'which' / 'where' I live in?

[Mehrgan]

Hi all,

In a test the answer to this question was 'which', and I hope someone will kindly tell me why! :--(

The place where I live.
The place which I live in.

You can't live a place, only live in a place. Relative 'where' can mean 'at/in which'.

Thanks a lot!
