C
RAD
D
Prototype
Explanation: 

Detailed explanation-1: -Storyboards. Storyboarding is an excellent way of telling stories and guiding targeted customers through a user experience. A technique to be used for early prototyping, storyboards allow you to visualize how users would experience a problem or product and present it in a series of images or sketches.

Detailed explanation-2: -A prototype is a model or sample of a product made for the client’s evaluation and feedback regarding the desired finishing product. After studying the prototype, the client can decide on the features they need in the desired product. This methodology or SDLC model is called Software Prototype Model.

Detailed explanation-3: -Prototype models in the technology industry help understand and test the functionalities and feasibility of various products. They help developers get quick feedback from all stakeholders including, the end-users and implement necessary changes before creating the final product.

Detailed explanation-4: -The Prototyping Model is a Systems Development Methodology (SDM) that involves building, testing, and reworking a model output. It is one of the most popular Software Development Life Cycle Models (SDLC models). The prototype works as a version on which various tests are conducted, and improvements are made.

Detailed explanation-5: -Rapid (Throwaway) prototyping. Evolutionary prototyping. Incremental prototyping. Extreme prototyping.

Detailed explanation-6: -Regardless of the needed fidelity, most prototypes will go through five distinct stages: defining, focusing on features, production, testing, and presenting.
