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
