Explanation:

Henry Ford is known for the assembly line method in automobile production. This method revolutionized manufacturing by making production faster, cheaper, and allowing goods (cars, in his case) to be sold at lower prices. The first option is about radio (not Ford's focus), the third is about electrical goods (not his main contribution), the fourth is about mechanization for suburbs (not his key industry impact). The assembly line is his major industrial contribution.

Answer:

His assembly line method of production allowed for goods to be produced faster and more cheaply and sold for a lower price
