Answer:
B) purchasing; accounts payable; cashier.
Explanation:
The purchasing department's role is to purchase all the necessary inputs needed for production or daily operation.
The accounts payable department's role is to control expenses, process, verify and reconcile invoices.
The cashier department's role is to receive and distribute money and funds.
The logic behind separating roles and responsibilities is that no single department can decide on what to spend, who the vendor will be and how much they should pay.
