A basic principle of operation of the synchronous counter is:
A) The J = K inputs are connected so that every other flip-flop will have J = K = 1 so they can toggle on the input clock pulse.
B) The J-K inputs are connected so that only those flip-flops that are supposed to toggle or a given clock pulse will have J = K = 1.
C) The J-K inputs are connected so that J = 0, K = 1 so they can toggle on a specific clock pulse.
D) The J-K inputs are connected so that ALL flip-flops will have J - K = 1 so they can toggle on each input clock pulse.
