Answer: A. The default gateway, 192.168.1.1
The host first uses its own IP address and subnet mask to decide whether the destination is on the same network. 203.0.113.80 is outside 192.168.1.0/24, so the packet is handed to the default gateway (a router). The destination in the IP header stays the server's 203.0.113.80; only the frame's destination MAC address is set to the gateway's. So ARP looks up the MAC address of 192.168.1.1. ARP broadcasts do not cross routers, so the host cannot look up, and does not need, the MAC address of a server on another network. Each router along the path looks up the MAC address of the next device whenever it forwards.
203.0.113.80 is outside 192.168.1.0/24, so the packet is handed to the default gateway (a router).
