I thought it was for source addresses too, but A makes sense.

I vaguely recall something about ARP and encapsulation, but I can't remember if it was Layer 3 or Layer z. This is tricky!

I feel like I mixed up Layer 3 and Layer 2 concepts in my studies. Is it really about the Layer 3 header?

I think it's about discovering the destination address, so maybe option A? That sounds familiar from our practice questions.

I remember ARP is used to map IP addresses to MAC addresses, but I'm not sure which option directly relates to that.
