Ans: C

Exp : As in the question it is clearly given that it is a single token architecture. So, it would be different approach to add new node to the existing cluster. There are basically two approach.

1. Add capacity by doubling the cluster size: This is one of the best approaches to increase the capacity of single token architecture cluster. Or you can even do the tripling, quadrupling the number of nodes. And this is a less complicated approach. With this approach existing nodes keep their existing token assignments, and the new nodes are assigned tokens that bisect the existing token range.
