How does the definition of BCNF differ from the general definition of 3NF? A. It requires all RHS to be non-prime and reduces functional dependency enforcement. B. 3NF allows dependent prime attributes where BCNF does not. C. In FD X A, 3NF condition allowing A to be prime, is absent from BCNF D. BCNF every functional dependency member will be a super key. 3nf can be canidate keys E. BCNF doesn't allow overlapping candidate key 3NF does. BCNF is also not always achievable
