Answer: C. Psychographic
Step-by-step explanation:
Psychograhic is the grouping of a population based on attitude , Interest and motivation, the demarcation in this scenario is based on students spirits, diversity and what they enjoy doing.
It's not a geographic demarcation because it's not based on physical boundaries or countries, it's not demographic because it's not based on natural factors such as ages, sex, etc . It's not based on equal consumption pattern and this makes it not to be behavioral and all the alternatives cannot be right because they are all different.
