Show answerHide answer

Correct answer: (C) Master-slave JK flip-flop

Explanation

In a JK flip-flop, when J = 1 and K = 1, Q toggles between 0 and 1 continuously as long as the clock is enabled, so the final value of Q is uncertain (race condition). The master-slave JK flip-flop is used to resolve this problem.
