Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

GRANT SELECT ON db_name.* TO 'user'@'%';

The GRANT SELECT ON db_name.* TO 'user'@'%' command grants SELECT privilege on all tables within the specified database to the user. Option A is incorrect because ALTER USER with GRANT OPTION is used to change user attributes or grant the ability to grant privileges, not to directly grant SELECT. Option B is incorrect because CREATE USER only creates a new user without assigning any privileges. Option C is incorrect because REVOKE ALL PRIVILEGES removes all privileges from the user, which is opposite of the desired action.
