Quizplus · Accepted Answer

The most commonly used notation to indicate cardinality in an ERD is (min, max) notation. This notation shows the minimum and maximum number of entities that can participate in a relationship. For example, (0,1) would indicate that an entity can participate in the relationship with no minimum and a maximum of one. (1,*) would indicate a minimum of one and an unlimited maximum. Therefore, choice B is the correct answer.
