Asynchronous down counters:
A) require that the LSB flip- flop change states with each input clock pulse the same as an up counter.
B) require that the MSB and LSB flip- flops change states with each input clock pulse.
C) require that the MSB flip- flop change states with each input clock pulse the same as an up counter.
D) require that each flip- flop change states with each input clock pulse.

Asynchronous down counters are designed so that the least significant bit (LSB) flip-flop toggles its state with every clock pulse, similar to how it operates in an up counter. This ensures that the counter counts down correctly, with changes propagating through the flip-flops from the LSB to the most significant bit (MSB) in a ripple effect.
