Step 1: The relation R is already in 1NF, since all its values are atomic.

Step 2: Converting into 2NF form. A relation schema R is in second normal form (2NF) if every non-prime attribute A in R is fully functionally dependent on the primary key

Step 3: Converting into 3NF. A relation schema R is in third normal form (3NF) if it is in 2NF and no non-prime attribute A in R is transitively dependent on the primary key

This is the final solution in 3NF.
