Explanation:

A prototype is a preliminary model or sample of a product or design to test its functionality, form, etc. A list of parts is just a compilation of components and not a model representing the actual product or its features for testing purposes. The other options are physical or visual representations for testing aspects like fit, feel etc.

C. a list of parts for building the engineering solution
