Quizplus · Accepted Answer

A non-rival good is one that can be used by multiple people without reducing its availability to others. Examples of non-rival goods include knowledge, ideas, and information. Option C, an idea for a new chemical formula for a drug, fits this definition as it could be shared and used by multiple pharmaceutical companies without reducing its availability to others. Options A and B, a pizza and a printing press, respectively, are rival goods because once they are consumed or used, they are no longer available for others to use.
