Answer:
c. Niche-picking.
Step-by-step explanation:
The psychological theory that an individual chooses the environment that best complements his/her hereditary is known as niche-picking. This means that a person chooses what is best suited to his/her interests and lifestyle. This can be seen in the case of extroverts reaching out or getting involved with people like themselves.
In the given case of Marvin, his decision of getting involved with people who love the same sport as himself is an example of niche picking. His tendency to chose "circumstances where he would be exposed to peers who also enjoyed hockey" means he's more prone to be involved with the same circle of people who love hockey.
Thus, the correct answer is option c.
