Ans : B
Exp : You require repair in the Cassandra cluster when replicas across the nodes are not in sync. There could be multiple reason for this, like one of the nodes is offline for some time and got reconnected to the cluster. Similarly, there are some drops in the write of the data then also you need to initiate the repair.
