What happens when an index cluster peer freezes a bucket?

When an index cluster peer freezes a bucket, it means that the bucket has reached the end of its retention period and is either deleted or archived, depending on the configuration. When a bucket is frozen, the cluster master will no longer perform fix-up activities for the bucket, such as replicating it to other peers or promoting it to primary. The cluster master will also update its list of buckets and remove the frozen bucket from the peer’s inventory. Therefore, the correct answer is C. The cluster master will no longer perform fix-up activities for the bucket. References:
