Wait, 15 read-only nodes? That sounds like a lot. I'm going to go with C, 10 seems more reasonable for a PolarDB cluster.

Hmm, this seems like a tricky one. I'm guessing the answer is B, since 5 is a nice round number for a cluster, right?

I agree with Michel, C) 10 makes sense for better scalability and fault tolerance.

I believe it's C) 10 because having more read-only nodes can improve read performance.
