What does the term serialization delay refer to?

A.
a fixed delay referring to the time it takes for a frame to transit the physical media

B.
a fixed delay referring o the time it takes to encode bits of packets onto the physical interface

C.
a variable delay caused by packet loss across a congested serial WAN link

D.
a variable delay caused by the processing tasks of a network device, such as route lookup, header changes, and switching

Explanation:

Serialization is the process of placing bits on the circuit. The higher the circuit speed, the less time it takes to place the bits on the circuit. Therefore, the higher the speed of the link, the less serialization delay is incurred.
