I was torn between A and B, but arp is more specific.

I disagree, iwlist is more for wireless info, not IP/MAC.

I'm confused about ipadm and iwlist; I don't recall them being used for this purpose, but I could be mistaken.

I feel like I've seen a question similar to this before, and arp was definitely the right choice for listing devices on the local network.

I remember practicing with ifconfig, but I don't think it lists both MAC and IPv4 addresses together like arp does.

I think the command to list MAC addresses is arp, but I'm not entirely sure if it also shows IPv4 addresses.
