Explain why. If not in 1 NF, normalize the above relation to 1NE. a. Is the above relation in the second normal form (2NF)? Explain why. If not in 2NF, then normalize to 2NF. Is the relation now in the third normal form (3NF)? Explain why. If not in 3NF yet, then normalize to 3NF. C. DO NOT assume any multivalued/composite attributes. Everything is clearly mentioned in question, answer accordingly.
