Q(next state)=JQ^+K^Q.
so the truth table of J K flip flop will be :-
J K Q(next state)
0 0 no change(Q)
0 1 reset(0)
1 0 set(1)
1 1 toggle(Q^)
so the truth table of J K flip flop will be :-
J K Q(next state)
0 0 no change(Q)
0 1 reset(0)
1 0 set(1)
1 1 toggle(Q^)

What is the meaning of inputs of j k flipflop cycle?

Assume J=0 and K=1
When cycle it, it becomes as J=1 and K=0.
When cycle it, it becomes as J=1 and K=0.

Why can't the answer be toggle ?

@Sundar clue is correct but small changes.
After one cycle the value of each input comes to the same value
ex: Assume J=0 and K=1.
After 1 cycle, it becomes as J=0->1->0(1 cycle complete) and K=1->0->1(1 cycle complete).
So answer is B. not change o/p.

@Ravi sinha tabe is right. When they form in cycle they form in 1 & 0 so output become no change.
