Consider the 1ollowin8 relation:
CAR SALE (Car_id, Option_type, Option_listprice, Sale_date, Option_discountedprice)
This relation refers to options installed in cars (e.g., cruise control) that were sold at a dealership, and the list and discounted prices of the options.
If CarlD Sale date and Option _typo Option_hstprica and CarlD, Option_type Option_discountedprice, argue using the generalized definition of the 3NF that this relation is not in 3Nf. Then argue from your knowledge of 2NF, why it is not even in 2NF.
