In DCL (Data Control Language), there are two types of privileges. This means that users can be granted or denied access to certain actions or operations in a database. The two types of privileges are: 1) System privileges, which control actions that affect the overall database system, and 2) Object privileges, which control actions that affect specific objects within the database, such as tables or views.

A. Object

Explanation

The privilege that means privileges on objects such as tables, views, synonyms, and procedures is "Object." This privilege allows users to perform various actions on these database objects, such as querying, modifying, or deleting data. It grants control over the specific objects within the database and their associated operations.

The other statements, "Revoke", "Permit", and "Create", do not specifically create a session for a username.
