Consider the relation r(a, b,c, d) with fds a -> b, c -> d, ad -> c, bc -> a. check for both bcnf and 3nf status. which of the following is the most accurate summary of the results? o ris in bcnf and 3nf. no normalization is necessary. o ris in 3nf but not in bcnf. we should try normalizing to bcnf, but this results in information being lost. as such, we stay with the original schema. o ris in bcnf but not in 3nf. since bcnf is the stricter normalization standard we do not need to normalize further. ris in neither bcnf nor 3nf. we need to normalize until the relations are in bcnf and/or 3nf.
