How can replication be restored?

A : The slave relay logs should be deleted; then execute START SLAVE;

B : The relay logs from the master should be used to replace the corrupted relay logs.

C : The slave relay logs should be deleted; execute CHANGE MASTER to adjust the replication relay log file name, then issue start SLAVE;
