8. 8. Consider the following relation instance of the CAR relation schema:

a. What is the minimal cover of functional dependencies that exists in CAR?

b. What is (are) the candidate key(s) of CAR?

c. If there is more than one candidate key, select a primary key from among the candidate keys.

d. Based on the primary key, what is the immediate Normal Form violated inn CAR?

e. Develop a dependency-preserving solution that eliminates this Normal Form violation. Is your solution a lossless-join decomposition?
