Answer:
a. production work on an assembly line that makes a product
Step-by-step explanation:
A support department refers to a section of an organization that comprises of employees who are saddled with the responsibility of providing timely and professional assistance to other core departments such as the production department.
This ultimately implies that, the support department provides assistance such as maintenance work done to keep production machines running smoothly, safety and security services provided to keep the production facility safe and janitorial services provided for the production facility.
Hence, any production work on an assembly line that makes a product is not a type of work done in a support department because all production work is solely being performed by the production department.
