Quizplus · Accepted Answer

The binary constraint is a constraint that must be satisfied for a ternary relationship. It specifies a set of value combinations that must occur in a binary relationship between two entities that participate in the ternary relationship. Therefore, choice B is the correct answer. The other choices are incorrect because they either mention specific relationships or tables that may or may not be relevant to the binary constraint.
