The correct answer is A. NotEnoughReplicasException. With replication.factor=3, min.insync.replicas=2, and acks=all, at least 2 in-sync replicas must acknowledge a write for it to succeed.

Explanation

With replication.factor=3, min.insync.replicas=2, and acks=all, at least 2 in-sync replicas must acknowledge a write for it to succeed. If 2 brokers are down, only 1 replica is available, which is not enough to meet the min.insync.replicas requirement. As a result, the producer will receive a NotEnoughReplicasException indicating that the required number of in-sync replicas is not available to safely commit the message.
