For relation R(A, B, C, D, E, F) the set of FD’s is{A → C, ...
(FD) is a set of functional dependencies that describe the relationships between the attributes in relation R. A functional dependency is a constraint that states that the values of certain attributes determine the values of other attributes.

The set of FD for relation R(A, B, C, D, E, F) could be as follows:

1. A -> B: This means that the value of attribute A determines the value of attribute B. For every combination of values of A, there is a unique value of B.

2. CD -> E: This means that the combination of values of attributes C and D determines the value of attribute E. For every combination of values of C and D, there is a unique value of E.

3. B -> F: This means that the value of attribute B determines the value of attribute F. For every value of B, there is a unique value of F.

These are just examples of functional dependencies and there could be other dependencies depending on the specific requirements and constraints of the relation R.
