The correct choice is (d) Both A many-to-many relationship set and A multivalued attribute of an entity set Explanation: For a many-to-many relationship set each related entity set has its own schema and there is an additional schema for the relationship set. For a multivalued attribute, a separate schema is created consisting of that attribute and the primary key of the entity set.
