When adding a node to the ring, data must move. What happens to latency during this transfer?

1. A Latency drops immediately as the cluster capacity increases, resulting in a sudden burst of improved response times.
2. B Latency remains entirely unaffected because data movement occurs within a dedicated, background high-speed fiber ring.
3. C Latency typically increases as the network and disk I/O are saturated by the 'bootstrap' process of streaming data to the new node.
4. D The cluster becomes temporarily read-only for all geographic regions until the tokens have fully converged across the gossip layer.
