One of the major drawbacks to the use of asynchronous counters is that:

[A]. low-frequency applications are limited because of internal propagation delays
[B]. high-frequency applications are limited because of internal propagation delays
[C]. Asynchronous counters do not have major drawbacks and are suitable for use in high- and low-frequency counting applications.
[D]. Asynchronous counters do not have propagation delays, which limits their use in high-frequency applications.

Answer: Option B

Asynchronous counter has higher propagation delay. Propagation delay is inversely proportional to frequency.

Therefore asynchronous counter has lower frequency. That denotes higher frequency are limited. If my answer is wrong. Please correct it.
