Which of the following is known as a set of entities of the same type that…

In database systems, an entity set refers to a collection of entities of the same type that share the same attributes or properties. For example, in a university database, the 'Student' entity set includes all students, each with common attributes like student ID, name, and age. A relation set is a collection of relations, not entities. Tuples are individual records within a relation, not a group of entities. The Entity Relation model is a design framework, not a set of entities. Therefore, the correct answer is the one that defines a group of same-type entities with shared attributes.
