    RELAY_LOG_POS=1383

Which command set would make the slave current?


A.

STOP SLAVE; SET GLOBAL master_delay=0; START SLAVE;


B.

STOP SLAVE; CHANGE MASTER TO RELAY_LOG_FILE = ‘hostname-relay-bin.00004’,

RELAY_LOG_POS = 1383;


C.

STOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; START SLAVE;

STOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; RELAY_LOG_FILE = ‘hostname-relay-bin.00004’, RELAY_LOG_POS = 1383;
