Quizplus · Accepted Answer

In an REA diagram, the maximum cardinality of a relationship between two entity sets can be either one or many. This means that there can be one or more instances of one entity set linked to one or more instances of another entity set through that relationship. For example, a customer can make one or more orders, and an order can have one or more line items. This is the most common type of relationship in an REA diagram. The other options (A, C, and D) are not correct because they do not reflect the typical behavior of relationships in an REA model.
