Q. Which of these is categorized under the ITeS sector?
Answer: Business Process Outsourcing (BPO)
Notes: Business Process Outsourcing (BPO) involves outsourcing non-core business activities using IT-enabled infrastructure. BPO is classified under Information Technology enabled Services (ITeS). ITeS covers services like BPO, call centers, KPO, and back-office operations. Semiconductor fabrication and hardware manufacturing are part of electronics manufacturing. Operating system development is a core IT/software activity, not ITeS.
