The relation is in
| First normal form but not in second normal form
| |
| Second normal form but not in third normal form | |

| |
| BCNF |
Question 820 Explanation:
Primary key of given relation is “ab”.
And there is a partial dependency exist in given FD’s so the given relation is in 1NF but not in second normal form.
