The race-around condition in a JK flip-flop occurs when

AJ = 1, K = 0 and the clock pulse is short
BJ = K = 1 and the clock pulse is longer than the propagation delay
CJ = K = 0 and the clock pulse is long
DJ = 0, K = 1 and the clock is edge-triggered

Correct answer: B

Explanation

With J = K = 1 the output keeps toggling during a long level-triggered clock pulse; edge triggering or master–slave design avoids it.
