An advantage of using interchangeable parts is that they a. make it easier to repair machines. b. are custom made to fit each machine. c. are made out of cheaper materials. d. are easier to work with.

The answer is: A. make it easier to repair machines.

Interchangeable parts are essentially made so the parts can be used to replace other parts on the same type.

For non-interchangeable parts, the only way for costumers to replace the parts is by ordering it directly from the manufacturer. With interchangeable parts, they can find the parts on the nearest repair shop.
