1.	If K → R then K is said to be the _______ of R(a) Candidate key(b) Foreign key(c) Super key(d) DomainI had been asked this question in unit test.This question is from Decomposition Using Functional Dependencies in section Relational Database Design of RDBMS
Answer» The correct CHOICE is (c) Super key For explanation I would say: If K →R then k is said to be the superkey of R i.e. K uniquely identifies EVERY tuple in the relation R.
