Which of the following represents the degree of the relation?Select one:a.Domainb.Cardinalityc.No of rowsd.No of Attributes

To determine which option represents the degree of a relation, let's analyze the options provided:

1. Domain: This refers to the set of permissible values that an attribute can hold. It is not related to the degree of the relation.

2. Cardinality: This term describes the number of tuples (or rows) in a relation, not the degree.

3. No of rows: This directly refers to the count of records in the relation, correlating with cardinality.

4. No of Attributes: This refers to the count of fields (columns) in a relation, and it actually defines the degree of the relation.

Conclusion:

The correct answer is d. No of Attributes, as it represents the degree of the relation. In relational database theory, the degree of a relation is defined as the number of attributes (columns) it has.
