The session is rolled back after receiving the error and JIM can continue with his transaction.

SCOTT has to reexecute the last command in the transaction after he commits the transaction.

The user HR owns the EMP table. The user HR grants privileges to the user SCOTT by using this command：  SQL> GRANT SELECT，INSERT，UPDATE ON emp TO scott WITH GRANT OPTION； The user SCOTT executes this command to grant privileges to the user JIM： SQL> GRANT SELECT，INSERT，UPDATE ON hr.emp TO jim；  Now， the user HR decides to revoke privileges from JIM using this command： SQL> REVOKE SELECT，INSERT，UPDATE ON emp FROM jim； Which statement is true after HR issues the REVOKE command（）

A、The command fails because SCOTT still has privileges.
