Answer 1

Answer 2

B

Answer 3

Well, all squares are rectangle, but all rectangles are not squares. But if it's not a rectangle, it's definitely not a square.

Similarly, all sergeants are fit, but all fit people are not sergeants. So, Harry inspite of clearing the fitness test, may or may not a sergeant. but if he hasn't cleared the fitness test, he DEFINITELY isn't a sergeant.
So, should be 'B'.

Can you 'feel' the analogy?
