Sir I didn't understand the 2nd diagram. Here we can't tell that some mammals are men too. That not given in statement. As I know that we can't think anything extra that's not given. Is it a case of possibility ?

All men are mammals also be true answer.

What about the possibility of some men are mammals?

Third possibility is that no mammals can be vertebrates or men.

why can't all men who are vertebrates, also be mammals? In my opinion, there are three possibilities, not two.
