b. Let the relation R = {M, N, O, P} be given with the multivalued dependencies N and M N. Assume that an expression R of the relation R contains the tuples ('m', 'n', 5, 5) and ('m', 'n', 4,6). What other tuples must R contain for the given dependencies to apply? C. Do the following multi-value dependencies also apply in (b)? (i) N MP (ii) (ii) M P (iii) (iii) M NP Justify your answer by specifying the inference rules used. d. Given the relation R = {V, W, X, Y, Z} with the functional dependencies VZW , Z XY, WZ V and the multivalued dependency XY Z. Is R in the 4th normal form? Justify your answer and, if necessary, state a lossless decomposition in fourth normal form
