Oracle permissions about usage with admin option and with GRANT option ____oracle

1, with admin option
With admin option means that the user granted this permission has the right to grant a permission (such as create any table) to another user or role, and cancellation is not cascaded.
If you grant a system permission to create session with admin option, and a then grant the Create session permission to B, but the administrator reclaims A's create session permission, B still has the Create session permission. However, an administrator can explicitly retract the permissions of the B create session, that is, directly revoke create session from B.

2, with GRANT option
With GRANT option means that the permission grant/cancellation is cascading, and if the WITH GRANT option is used for object authorization, the granted user can also grant the object permission to another user or role, except that the administrator reclaims the WITH grant Option authorizes User object permissions, permissions are invalidated by propagation, such as grant Select on table and Grant option to a,a users give this permission to B, but when an administrator reclaims A's permissions, B's permissions are invalidated. However, the administrator can not directly retract the Select on TABLE permission for B.
