The automobile company announced that the average price of next year's models would decrease four-tenths of one percent, amounting to about $72, as compared with comparably equipped cars and trucks this year.

Option A is wrong because it compares the average price to both cars and trucks. This makes this option wrong.

Option B is the preferred option because of the use of "that" which means the average price, making the comparison to be appropriate.
