The correct answer is option 3.

Key Points

Corrective, adaptive, perfective, and preventive maintenance are the four forms of maintenance.

  • Corrective maintenance focuses on resolving issues that arise when the programme is in operation.
  • Adaptive maintenance is concerned with the changes made to the software in order to make it adaptable to new environments, such as running it on a new operating system.
  • The term "perfective maintenance" refers to the changes in the software that occur as a result of adding new features.
  • Preventive maintenance entails making adjustments to avoid mistakes from occurring. The following graph shows the distribution of maintenance types by type and percentage of time spent.

∴ Hence the correct answer is Perfective maintenance.
