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

• 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 and this limits their use in high-frequency applications
