Check one by one...
option A:- D->AB
Now My Functional Dependency set is {B->C and D->AB} therefore D is the Key for the relation, now B->C leads to non-prime transitivity, therefore It is not in 3NF
option B:- AC->D
Now My Functional Dependency set is {B->C and AC->D} therefore AB is the Key for the relation, now B->C leads to partial functional dependency, therefore It is not in 2NF ===> It is not in 3NF
option C:- CD->B
Now My Functional Dependency set is {B->C and CD->B} therefore ABD or ACD are the Keys for the relation, now B->C leads to prime transitivity, therefore It is not in BCNF but It can in 3NF
option D:- AD->B
Now My Functional Dependency set is {B->C and AD->B} therefore AD is the Key for the relation, now B->C leads to non-prime transitivity, therefore It is not in 3NF.
Option C is correct
