Which inventor is associated with popularizing the assembly line in industry?

• A. Thomas Edison
• B. Alexander Graham Bell
• C. Eli Whitney
• D. Henry Ford

Answer: (D)

Henry Ford popularized the moving assembly line as a way to mass-produce goods. By having the product move along a conveyor and assigning workers to simple, repetitive tasks at each station, production time dropped, parts could be standardized, and costs fell. This approach made cars more affordable and showed how mechanized, repetitive work could dramatically scale manufacturing across industries. The other inventors listed contributed important innovations in electricity, communication, and interchangeable parts, but Ford is the one who demonstrated and spread the efficient assembly-line method that reshaped industry.
