AnswerB
ExplanationAttributes in a database represent the properties (names, values, or characteristics) of an entity.
Example Usage:
In a Students table, attributes might include:
StudentID (Primary Key), Name, Age, Major
Here, Name is an attribute describing the entity Student.
Why Other Options Are Incorrect:
Option A (Synonyms) (Incorrect): Synonyms in SQL allow different names for the same object but are not attributes.
Option C (Repositories) (Incorrect): A repository stores data but does not define attributes.
Option D (Relationships) (Incorrect): Relationships define connections between entities, not their attributes.
Thus, the correct answer is Names, as attributes define entity properties.
