Then which of the following flip-flop is likely to avoids the race around condition:

Solution
The correct option is D D
Race around condition occur in JK flip-flop when J = K = 1. This can be avoided if the propagation delay of flip-flop is more than pulse-width of the clock but less than the clock time period.
Ideal condition is 2tp<Δt<T.
Which is satisfied in option (d) only
