b) Given the relation R(A, B, C, D). The functional dependencies

b) Given the relation R(A, B, C, D). The functional dependencies that hold are: A B B C AC B BD A D R has only one candidate key and it is A. 1. [1 pt] Explain why R is not in 3NF. Write no more than 2 lines. Because there are transitive dependencies in the ED Set Hence R is not in 37 2. [2 pts] Give 3NF decomposition for R. You must justify every step in your work.
