Answer: (B)

Henry Ford is associated with the assembly line, which he popularized and perfected to create mass production of cars. The moving assembly line organized work into simple, repetitive steps on a conveyor, dramatically cutting production time and costs. This transformation made affordable automobiles and demonstrated how mechanized processes could build a modern consumer economy. The other figures connect to different fields: Edison is famous for electric light and sound recording, Rockefeller for dominating the oil industry, and Bell for inventing the telephone.
