b. Prototyping refers to the process of developing a working replica of the system or some aspect of the system.
Step-by-step explanation:
A prototype is a sample used by the system analysts or users to evaluate the new design or build to determine its precision. A prototype is a trial product or software that is widely used in software programming and electronics.
The accuracy of the newly developed product can be checked with the help of prototype. Prototype is the replica of the real product. It helps in correcting design error before its production. Consumer gets easily attracted by seeing the prototype before the release of the original product.
