I guess option A could work if it was a source-based routing scenario, but in a typical unicast forwarding case, it's all about the destination IP, baby!

Lol, option E? Seriously? The inbound port? That's just silly. Routers care about the IP destination, not the physical port.

I'm going with option C. The destination IP address is definitely the key information the router compares to make its forwarding decision.

Exactly, it helps the router determine the next hop for the packet.

Yeah, that's why the destination address of the IP header is compared with the routing table entries.

I agree, the router needs to know where to send the packet based on the destination IP address.

I think option C is correct too. The destination IP address is crucial for routing.

I'm not sure, but I think it might also be A) The source address of the IP header, to ensure the packet is coming from a valid source.

Hmm, the destination address of the IP header seems like the logical choice here. That's what the router uses to look up the appropriate path in the routing table.
