Answer:
c. machining.
Step-by-step explanation:
Unit level activities take place in order to manufacture the product. This manufacturing process has four activities:
- engineering
- setups
- machining
- inspecting
Unit level activities depend on the amount of units produced, this means that as more units are produced, more costs will be allocated. In this case, engineering, setups and inspecting are done on a batch basis, which means that they are batch level activities.
Only machining costs are proportional to the number of units produced.
