On the network shown in the figure, the router receives a data packet with the destination IP address 11.0.12.1 from Host A. After the packet is forwarded by the router, which of the following are…

The correct answer is C. MAC-B, 11.0.12.1. When Router A forwards the packet to Router B, the destination IP address (11.0.12.1) remains unchanged as it is still meant for Host B. However, the destination MAC address changes to MAC-B, which belongs to Host B, since MAC addresses are only used for local network hops.
