A,C Correct answer
Explanation

DCL (Data Control Language) commands in SQL are used to control access to data. GRANT gives permissions and REVOKE removes permissions - both are correct DCL commands. ALTER is a DDL (Data Definition Language) command, not DCL. Option D ('All of the above') is incorrect because ALTER is wrong.
