2. In a network, Host A and Host B are connected through Routers R, and R2 (i.e, A> R] R2 +>B). Which of the following statements are true: (A) If A sends an IP datagram to B, the value of the TTL field cannot be less than 3. (B) If A sends a IP datagram to B, the destination address in the IP and the MAC headers will be that of R1 (C) If A sends a datagram to B through R, and ICMP redirect is received, Host A, R, and R2 are all on the same LAN segment. (D) Host A sends a datagram to Host B with TTL set to 1, it will receive an ICMP error message with Destination Unreachable
