Correct answer: C
Answer: 65,495 bytes.
Explanation:
IPv4 Total Length field is 16 bits, so the maximum IPv4 packet size is 65,535 bytes.
Minimum IPv4 header length (no options) = 20 bytes.
Minimum TCP header length (no options) = 20 bytes.
Maximum TCP payload = 65,535 - 20 - 20 = 65,495 bytes.
Note: If IP or TCP header options are present the available TCP payload will be smaller. This calculation applies to IPv4; IPv6 uses a different header model.
