I think the answer is option 'C' because the clock pulse should allow the input to settle.

@Vijay.

I think it might be the one.

As there is a term of "propagation delay" related to flip flop which affects on the output of flip-flop, and if this rising and falling time is less. There is some possibilities of decreasing the propagation delay. That's why I think short time must be the correct answer.

Can anyone explain this? I thought there must be long enough time to stabilize?
