Match the following
16. Corrective -Concerned with fixing errors that are observed when the software is in use.
Adaptive - Concerned with the change in the software that takes place to make the software adaptable to new environment(both hardware and software)
Perfective - Concerned with the change in the software that takes place to make the software adaptable to changing user requirements.
Preventive - Concerned with performing activities to reduce the software complexity thereby improving program understandability and increasing software maintainability.
