Hi,
>>ddl and dcl statements are auto-committed
>>so options a,d and e r correct and u can choose any two in between them.
option a - delete is not a DDL statement... rather it is a DML statement and therefore are not comitted implicitly. the other two options are correct.
Revoke is not the option since it does not commit the changes; it undo whatever has been done since last commited transactions
