Answer:
C.the availability heuristic.
Step-by-step explanation:
Availability heuristics is the assumption that memory can accurately assess the frequency of an event, based on long-term memory recall.
In other words, the likelihood of an event is based on how easy it is for the person to remember a similar event. But recall could be caused by exposure to events, personal experience, and dread and familiarity of events. Therefore, people estimate the frequency of events and define the likelihood with these frequencies(Just like the Dean in this context).
