In a distributed system using the Raft consensus algorithm, what happens if the current leader becomes unreachable?

A Followers that stop receiving heartbeats from the leader will time out and initiate a new leader election, with a candidate becoming the new leader if it receives votes from a majority B The entire cluster permanently stops functioning until manually restarted by an administrator C All data in the cluster is immediately and permanently deleted D Every follower simultaneously becomes a leader with no election process
