Question

Is it who or whose to this sentence : Who’s/whose muddy foot prints are those ???

Answer 1

Question: Who's/Whose muddy footprints are those?

I think the answer would be "Who's".

Answer 2

Well, "who's" is who is, it's just a contraction. So, it'd be whose.

"Who is muddy foot prints are those?" doesn't sound correct, but

"Whose muddy foot prints are those?" does.

Hope this helps!
