To determine the correct answer to the question about an ERD (Entity-Relationship Diagram) and the type of model it represents, let's analyze each option:

1. **Data Integrity**: While data integrity is an important aspect of database design, it does not specifically describe a type of model. Therefore, this option is not correct.

2. **Conceptual**: ERDs are indeed a type of conceptual model. They represent the abstract design of a database in terms of entities and the relationships between them without going into the detailed physical structure.

3. **Network**: This refers to a specific type of database model that organizes data using graph structures, and is not what an ERD entails.

4. **Physical**: This model relates to how data is physically stored in a database, which is beyond the scope of what an ERD illustrates.

5. **None of the answers are correct**: Since we have established that option (b) is correct, this option cannot be right.

### Final Answer
The correct answer is **b. Conceptual**. An ERD is an example of a conceptual model used in database design.
