The answer must be D

The maintenance can be divided into four types:

  1. Correction: To correct defects.
  2. Adaptation:  If external environment (e.g., CPU, operating system, business rules) changes, software should be modified.
  3. Perfective: extends the software by adding extra functions. This type of maintenance needs maximum effort.
  4. Prevention: Due to the changes by other maintenances software can be easily degraded. Preventive maintenance makes changes to computer programs so that they can be more easily corrected, adapted, and enhanced.
