Real ZK developers will answer shortly, but your scenario is still a bit ambiguous. The results will differ depending on the context of the partition.
If the partition occurs after leader election and A is the leader, I don't think that operations will be impacted unless another leader election is initiated. If the partition occurs after leader election and B (or C) is the leader, then I think that C (or B) will think it has been partitioned from the net and freeze. A and B will continue to operate. If the partition occurs during or before leader election, I don't know what will happen, but my guess is that the election will succeed with a quorum and one of the two previous scenarios will apply.
