Answer:
C. repetitive production
Explanation:
Based on the information provided within the question it can be said that only in Repetitive Production will you see at most minor variations implemented. This is because this type of operations uses various machines in a pre-set process to make the product, a small change in the product specifications would require ALL of the equipment to be replaced, rearranged, or modified just to be able to implement the changes to the product. This many times costs more money than what the change will generate.
