Hmm, I wonder if the secondary nodes get jealous of the primary's write privileges. Healthy competition, I say!

I bet the arbiter node is so tired of being overlooked. Somebody give it a chance!

But what about the arbiter node? Doesn't it have a role in the replica set too?

C is the correct answer. I can't believe anyone would think an arbiter or hidden node would accept writes. That's just silly.
