Quizplus · Accepted Answer

When attribute A determines a single value for attribute B at any time, we say that attribute B is functionally dependent on attribute A. This means that the value of B can be determined based on the value of A. A is known as the determinant or parent, and B is known as the dependent or child. Option A is incorrect because it implies that A is the parent instead of B. Option D is incorrect because it does not accurately describe the relationship between A and B.
