B talks about numbers, but the argument centers around percentages (half = 50% and third = 33%). C is actually a counterargument: it means that it's not the quality of the car that accounts for its durability, but the "quality" of the owners. D is the only one that remains: not changing much means the cars are as durable as they've always been.

It really doesn't matter (at least not to me, I guess) what's the number of cars manufactured: if half or 50% of them are functioning as compared to a third or 33% of competitors' cars, then you know that Deluxe are better.

What's the OA?

Which of the following, if true, most strongly supports the advertisement's argument?
(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.
(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.
(C) Owners of Deluxe automobiles typically keep their cars well maintained.
(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.
(E) Deluxe automobiles have been selling at relatively stable prices in recent years.
