Selected Answer: B
The TTL field in the IP header is designed to prevent packets from circulating endlessly on a network. Each time a packet passes through a router (a "hop"), the router decrements the TTL value. If the TTL reaches zero, the packet is discarded, and an ICMP "Time Exceeded" message is usually sent back to the source
