A) ​A functionally determines B
B) ​A functionally determines another attribute in the table

D) ​B does not determine any other attribute

Quizplus · Accepted Answer

If B is functionally dependent on A, then the value of B is determined by the value of A. Therefore, we can say that A functionally determines B.

Option D is also incorrect as B may be the determinant for other attributes in the table.
