Question

____ car is that in the parking lot?
1 whose
2 who's
3 whos
4 who

Answer 1

Who car?? That can't be right, so D is wrong.

I don't think there is a simple plural for who. C is wrong.

B means who is. So B is not right either who is car is parked in ...

It is A or 1. Whose car ... Whose is a possessive pronoun. It is the answer.
