B
The flip-flop holding most significant bit receives incoming count pulse input and rest of flip-flops receive output of previous stage as count pulse input
C
The flip-flop holding least significant bit receives incoming count pulse input and rest of flip-flops receive output of previous stage as count pulse input
D
The flip-flop holding least significant bit receives incoming count pulse input and rest of flip-flops receive complement output of previous stage as count pulse input
