Show answer & explanation
Correct answer: A
The correct option is A (16). The checksum field in the Transmission Control Protocol (TCP) header has a fixed size of 16 bits (2 bytes). It is mandatory for error-checking, verifying the mathematical integrity of the TCP header, the payload data, and an additional pseudo-header.
