Answer

In database management systems, the three levels of data abstraction are:

2. Conceptual Level: This represents the entire database content, defining what data is stored and the relationships among those data. It provides a community view of the data.
3. External Level: This level includes various user views of the database, presenting data in a way that is meaningful to each user.

Given the options provided:
