Thanks :)

Answer 1

B) Uniquely identified a row  -> Candidate key

C) A constraint between two attribute -> Functional Dependency

D) Group of attributes on the left hand side of arrow of function dependency. -> Determinants

don't know about A but according to me no option given in the question is true.
