A. Incremental Development
Explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
The answer to this question is Incremental Development, this is when the development of the system is implemented little by little as time goes on. On the other hand phase development is when a development cycle is rolled out in phases such as the brainstorming phase, Construction phase, marketing , and roll out phase. Since this development doesn't contribute to the system's functionality it is not the correct answer.
