Synchronous counters eliminate the delay problems encountered with asynchronous counters because the:
input clock pulses are applied only to the first and last stages
input clock pulses are applied only to the last stage
input clock pulses are not used to activate any of the counter stages
input clock pulses are applied simultaneously to each stage
Answer: Option
