b) Concept testing
c) Prototype development
And the correct answer is the option C: Prototype development.
Step-by-step explanation:
On the one hand, the stage of "product screening" is when the company and its employees can pare down the list of viable ideas to the ones that will only match the organization's strategic goals that they are looking for.
On the other hand, the "prototype devolopment" stage involves the fact of getting those viable ideas into touchable models that the managers can try in real life experience more than just in the papers. Therefore that in this stage is when the employees build a product model based on clear product descriptions.
