Detailed explanation-1: -Maintenance is the final phase in waterfall model. Explanation: The statement is true. This is the phase in which the completed software product is handed over to the client.
Detailed explanation-2: -The waterfall model uses a logical progression of SDLC steps for a project, similar to the direction water flows over the edge of a cliff. It sets distinct endpoints or goals for each phase of development. Those endpoints or goals can’t be revisited after their completion.
Detailed explanation-3: -Maintenance. After the deployment phase, the next step is to provide support and maintenance for the software, making sure it runs smoothly. If the client and users come across errors/defects/bugs during use, fixing them is the main purpose of this stage.
