Question

which concept drastically changed the way that henry ford produced model t automobiles?
lowering the price of his products
inventing the quadricycle
creating a moving assembly line
using a skilled labor force

Explanation:

Henry Ford's moving assembly line revolutionized automobile production. It increased efficiency, reduced production time, and made mass - production of Model T cars feasible. Lowering prices was a result of increased production efficiency (from the assembly line), not the concept that changed production. The quadricycle was an early vehicle prototype. Skilled labor was less emphasized as the assembly line broke tasks into simpler, unskilled steps.

Answer:

C. creating a moving assembly line
