I feel like I've seen a question similar to this before, and it was about how nodes interact with the network. I think option A sounds right.

I think Ethereum nodes are related to how the network communicates, but I'm not entirely sure if they specifically implement the protocol.

Gain and polarization mode are definitely important, but I'm not sure about lobe width. I'll have to review my notes on antenna characteristics to make sure I'm not missing anything.
