In the past most automobile companies minimized the weight

I'm inclined towards E.

In the past most automobile companies minimized the weight of cars to reduce the cost of cars in their lines.

The safest car seats were heavier => less safer were ligher

=>minimized weight to reduce price
=>less safer were cheaper and ligher.

This year, the cheapest cars in most automakers lines included the safest seats on the market.

=>cheapest is safest.

A. Tells about weight but nothing about price, hence out
B. Out of scope
C. Out of scope
D. not possible
E. Safest seat was least expensive & thus could be installed in cheapest cars.

OA please?

Clearly A.

The makers are concerned with reducing the weight of the car. Even if safest seat is cheapest but very heavy, makers would not want to use it.
Hence E is ruled out.

OA is E

(B) No information was given by the argument about the best-selling cars in any year, thus this does not have to be true ・eliminate.
(C) No information was given about any seat other than the safest or about the price of materials, thus this does not have to be true ・eliminate.
(D) No information was given about what made the company use the safest seat in the cheapest cars, thus this does not have to be true ・eliminate.
(E) This choice is the best available.

A) or E) ?

why is the safest seat in the cheapest car ? the reason is because the safest seat is the least expensive one in the market. that`s E). so that the overall costs of the car stay low. why not A) ? because if the reason is the weight, then the automakers would put the safest seat in the expensive cars as well. but they don`t, because in a expensive car are mostly expensive parts. so if it would be E), then the cheapest as well as the most expensive cars would have this "safest" seat. but thats not the conclusion. so its not about the weight but about the price. and thats why its E).
