As the number of flip flops are increased, the total propagation delay of
ripple counter increases but that of synchronous counter remains the same
both ripple and synchronous counters increase
both ripple and synchronous counters remain the same
ripple counter remains the same but that of synchronous counter increases
Answer: Option
Explanation:

In ripple counter the clock pulses are applied to one flip- flop only.

Hence as the number of flip-flops increases the delay increases.

In synchronous counter clock pulses to all flip-flops are applied simultaneously.
