Quizplus · Accepted Answer

The correct answer is C because in an ER diagram, if a customer can refer many customers, it indicates a one-to-many relationship between the customer doing the referring and the customers being referred. This means a single customer can refer none, one, or multiple other customers, fitting the description of option C. Options A, B, and D are incorrect interpretations of such a relationship.
