What do you think? Please don't forget the explanation

An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today, compared to no more than a third for any other manufacturer.
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.

only B works here, since the argument does'n take into account inflation (a), care (c), competitors(d), prices (e)

IMO B.

If more than 50% of the automobiles built since 1970 still exists then it would be correct to assume that the number of automobiles since 1970 did not increase sharply.

(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.

Its B. Only B supports the argument by saying that, the no. of cars manufactured per year has not increased sharply. Lets say Deluxe only manufactured 3 cars in 1970. And this year it manufactured 30,000 cars. Now out of 3 cars, 2 run on the road today. B removes this possibility and so strengthens the argument.
