Correct option is C
Master slave JK flip-flop: The master-slave JK flip-flop configuration is specifically designed to prevent the race-around condition. It uses two JK flip-flops in a master-slave arrangement, where the master flip-flop is enabled on the clock's rising edge and the slave flip-flop is enabled on the falling edge. This ensures that the inputs are stable and the output changes only once per clock cycle, preventing race-around conditions.
