What describes the difference between Asynchronous and Synchronous Copy on First Write
(COFW)?

A.
Asynchronous mode results in fewer disk operations during COFW.

B.
Asynchronous results in a shorter host response time as there is no COFW penalty
compared to Synchronous.

C.
Asynchronous mode results in more disk operations during COFW.

D.
Asynchronous and Synchronous mode result in similar host response time as both suffer
the COFW penalty.
