Answer:
c. Niche-picking.
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<em> "circumstances where he would be exposed to peers who also enjoyed hockey"</em> means he's more prone to be involved with the same circle of people who love hockey.

Scintillation counters are widely used in medical imaging used to measure radioactive contamination, radiation measurement gauges, radiation measurement testing, nuclear power plant safety, and radiation.
Scintillation is the process by which the energy of a specific radiation interacting with a certain amount of sensitive material (called a scintillator) is converted into electromagnetic waves. The frequencies of the electromagnetic waves emitted are in or near the visible spectrum.
A scintillator is a substance that exhibits scintillation, the property of luminescence, when excited by ionizing radiation. When a luminescent material collides with an approaching particle, it absorbs the energy and glows (that is, it re-emits the absorbed energy in the form of light).
