Consider the following relation: R(A,B,C,D,E) The following set of functional dependencies are ture on the relation R: FD: AB -> E, E -> D, AD -> C Which of the following sets of attributes does not functionally determine C?
AC
ABE
BD
AE
AB
Homework Answers
Closure of each set of attributes
AC+=AC
ABE+=ABEDC
BD+=BD
AE+=AEDC
AB+=ABEDC
So here for BD only we didn't got C
So ans is BD.
