The functional dependency R → S means that the value of S can be determined when we are given a value of R.

Answer: Option A

Option1: True
The statement is correct. In a functional dependency R ? S, the value of S can indeed be determined when we are given a value of R. This is a fundamental concept in the relational model of databases.

Option2: False
This statement is incorrect. In a functional dependency R ? S, the value of S is dependent on the value of R. Therefore, the statement that the value of S cannot be determined when we are given a value of R is false.

Conclusion: The correct option is Option1: True. In a functional dependency R ? S, the value of S can be determined when we are given a value of R. This is a key concept in the relational model and normalization of databases.
