Show answer & explanation
Correct answer: A
The ANSI-SPARC architecture consists of three valid levels: External, Conceptual, and Internal. Administrator level is not a part of this three-level architecture; instead, a Database Administrator (DBA) is a user role responsible for managing the database system. Therefore, Option A is the correct answer.
