Final answer:
The student's example is an instance of consumer problem behavior, specifically product misuse, where chili powder is consumed in a harmful manner not aligned with its intended use. Correct option is d. consumer problem behavior.
Step-by-step explanation:
Morgan and her friends' game of daring each other to eat chili powder and withstand the discomfort without relief is an example of consumer problem behavior. This behavior includes activities that are contrary to generally accepted norms of consumption and which could be harmful to the individuals engaging in the activity.
The game they invented does not constitute compulsive consumption as it is not repetitive or chronic in nature, nor does it involve an inability to resist the consumption. Product misuse is a more accurate label for this behavior because it involves using a product, in this case chili powder, in a way that it is not intended to be used, and which could potentially result in harm.
