Answer:
d) a prototype
Step-by-step explanation:
A prototype is a preliminary version of a product that is used to evaluate and test its design and functionality before it is built. In software development, a prototype can be a working model of the software that allows developers to test its features and functionality before it is released to end-users.
Creating a fake website to test demand for a product is a common strategy used by startups and entrepreneurs to validate their ideas before investing time and resources in building the actual product. By creating a prototype website, they can gauge user interest, collect feedback, and make informed decisions about whether to move forward with the project or pivot their strategy.
In summary, a fake website created to test demand for a future product is an example of a prototype in software development.
