E is correct here

From st 1 you don't know how many cars were there by the end of the year.
From statement 2 you don't know how many cars have been purchased in the year

By combining 1 and 2 you don't know the quantity of the cars sold in the year and also what was the price of the sold car. So you can't get the answer. Therefore, E is correct.
