Given relation R(A, B, C, D, E) with functional dependencies AC -> E E-> C D -> E What is /are the key (s)? Note that if there are multiple keys, please write it in this format: Key1 and Key2. Do not use other punctuation marks. If the key includes multiple attributes, just write their concatenation. For example, if attributes X and Y constitute a key, then you should write XY or YX. Answer: Which statement is true? a. It is not BCNF because it is in 2 NF. O b. It is in BCNF Form. O c. It is not in Bch form because it is in 3 NF. O d. It is not in BCNF form because one of the determinants is key. O e. It is not in BCNF form because all determinants are not key Clear my choice
