Given a relation R(A, B, C, D, E) with functional dependencies: AB -> C and C -> D. a. Find all key(s) of the relation R. b. Which normal form is R in? c. If R is not in BCNF, decompose R, as necessary, into a set of relations that are in BCNF. d. Is your decomposition dependency-preserving? Briefly explain why or why not?
