The correct answer is C. Ford’s invention of the assembly line, decreasing their cost.

Explanation:

Before the implementation of the assembly line in the process of manufacture of cars by Henry Ford at the end of the 19th century, cars were only affordable by wealthy people as creating a car took many experts working together assembling one car at a time, this process make cars expensive, besides each car had unique parts that were really difficult to replace if needed. However, this changed as Ford invented and implemented the assembly line which implies unskilled workers each with one task and who participated in the process of assembling multiple cars at the same time. This reduces the cost and allowed middle-class people to buy cars and therefore make automobiles very popular.
