In SR-ff, both the input as 1 produces an indeterminate state which is not desired practically.

Hence, to overcome this, JK-ff is designed which toggles the present state when both the inputs are equal to 1.

Yes JK flip-flop accepts both inputs as 1 and in return gives a toggle state which means a complemented state as output. For ex - if the initial state is q then the output would be complement of q.

In case of SR flip-flop the output would be a invalid state if both the inputs are set to 1.

How it will be possible?

I think B is the correct answer, please clarify the answer properly.
