For a JK flipflop, when $J = 1, K = 1,$ output toggles.

When $J = 0, K = 1, Q = 0, \overline{Q} = 1.$

Since initially $Q = 1, \overline{Q} = 0,J = 0 $ and after first clock $Q = 0, \overline{Q} = 1.$

After second clock, $J = 1, Q = 1.$

And this sequence repeats.

So, correct answer D.

GATE Overflow Test Series | Mixed Subjects | Test 2 | Question: 17
In an SR latch made by cross-coupling two NOR gates, both $S$ and $R$ inputs are set to $1$, and then both are again set to $0$ after the output is stabilized. This will result in the output No change $Q = 1, Q' = 0$ $Q = 0, Q' = 1$ Indeterminate state
