Answer

The term that refers to the number of entities to which another entity can be related through a relationship set is called d. Cardinality.

Explanation

1. Understanding Cardinality: In the context of databases and entity-relationship models, cardinality defines the number of instances of one entity that can or must be associated with each instance of another entity.

2. Types of Cardinality: It is common to see cardinality expressed in three forms:

   • One-to-One (1:1): Each entity in the relationship can relate to one and only one entity from another set.
   • One-to-Many (1:N): An entity from one set can relate to multiple entities from another set.
   • Many-to-Many (M:N): Entities from both sets can relate to multiple entities from each other.

Conclusion

In summary, the correct answer is d. Cardinality, as it describes the relationships between entities in terms of quantity and multiplicity.
