TTL stands for Time to Live and is an 8-bit value in the IP header that represents the maximum amount of time the packet is allowed to remain in the network before it is dropped. It is used to prevent packets from circulating endlessly in the network. Each router decrements the TTL value by 1, and if it reaches 0, the packet is dropped. Therefore, A) TTL is the correct choice. B) Fragment Offset is a field in the IP header that specifies the position of the data in the original IP datagram. C) ECN (Explicit Congestion Notification) is a field in the IP header used to indicate network congestion to the sender. D) Options is a field in the IP header used for various purposes, such as timestamping, security, etc.
