  • A.Corrective maintenance
  • B.Perfective maintenance
  • C.Adaptive maintenance
  • D.Code maintenance

Answer: B

Improving processing efficiency or performance, or restructuring software to improve changeability, is perfective maintenance. It improves the software without a fault or a change of environment.

Corrective maintenance fixes faults, adaptive maintenance changes the software to suit a new environment, such as a new operating system, and code maintenance is not one of the standard categories. So perfective maintenance is the answer.
