Show answer & explanation
Correct answer: B
The Entity-Relationship (E-R) model is a conceptual framework used in database design. It fundamentally consists of three core components: entities, which represent objects; relationships, which define associations between these entities; and attributes, which describe properties of the entities or relationships. Therefore, the model is expressed in terms of all three listed elements.
