The interchangeability of parts:Select one:a. Look differently from existing parts but serve the same function. b. Fit mating parts but require some additional machining at the time of assembly. c. Are made to easily fit mating parts without additional machining at the time of assembly. d. Must be manufactured in other countries around the world and are assembled in the United States.

option C

Explanation:

I choose option c because they are made to fit mating parts easily and do not require further machining.

From the meaning of interchangeable parts, they mean that parts are created almost identical and they would easily fit the same purpose I.e we have part A and B, they are almost I identical . if A does a rotation work and gets faulty part B can easily fit into the part and perform the same work without any other machining.

The best answer that matches my explanation is option C.

i took very good i wish you luck! i hope it .
