BPO stands for Business Process Outsourcing — it involves contracting certain business tasks to third-party service providers.
Companies outsource activities to BPO firms to reduce costs, improve efficiency, and focus on their core business areas.
Generally, back office functions such as data entry, payroll processing, accounting, customer support, and HR services are outsourced.
These tasks are routine, repetitive, and require less direct customer interaction but are essential for smooth business operations.
Front office activities, on the other hand, deal directly with customers (like sales or client meetings) and are less likely to be outsourced to BPOs.
Middle office functions often involve risk management and compliance, which are also usually kept in-house.
Hence, option (A) Back office is the correct answer.
