Option D makes the most sense to me. No need for Ethernet when the routers can talk directly over the PPP link. Gotta love those networking shortcuts!

D is the way to go. PPP links can communicate directly without the overhead of Ethernet headers and ARP. Saves a lot of time and resources.

Haha, the question is so confusing, I feel like I need a Ph.D. in networking to understand it. But I'll go with D, it sounds the most logical.

I think the answer is C. The LCP protocol allows the interconnect ports to learn the MAC addresses of the other end, so no ARP is needed.

D) The data packets of the interconnect POS ports of R1 and R2 do not need to encapsulate ethernet headers and do not need to use ARP to request MAC addresses

The correct answer is D. The PPP links between R1 and R2 do not need to use Ethernet headers or ARP since they communicate directly at the network layer.

Interesting point, Reuben. But I still think option A makes more sense in this scenario.
