Answer: None of the above.
Step-by-step explanation:
The correct answer will be "None of the above." The person who handles cash cannot issue credits to customers on sales returns. This could be because their job function does not include this process.
The person also may not account for cash receipts to customers. They can also not account for cash purposes. This could also be because these processes are not included in the persons job function or duties.
Each job function has a clear set of duties that one can perform. Each business has different jobs for people and this particular one does not allow for the person handling cash to do anything else.
