SPX is not network layer, it's transport. So A, B, and D for sure!

Yeah, I agree! RIP and OSPF are routing protocols. IGMP is for multicast.

I’m pretty confident that both RIP and OSPF are correct, but I’m torn between IGMP and SPX for the third option.

I feel like IGMP is related to multicast, so it might be a network layer protocol too, but I can't recall for sure.

I remember practicing a question where we had to identify protocols by layer, and I think SPX is more of a transport layer protocol.

I think RIP and OSPF are definitely network layer protocols, but I'm not sure about IGMP.
