Correct Answer: None of the above
Explanation:
Functional Dependency:
It is a relationship between two attributes in which the right-hand side attribute is functionally dependent on the left-hand side attribute.
If the value of attribute Y is determined by the value of X then it is represented as given below:
X → Y
