Final answer:
A person is most likely to use heuristics when the decision is of relatively little importance and must be made quickly, corresponding to option b). Heuristics are cognitive shortcuts like choosing a candidate from a preferred political party or selecting the daily special at a restaurant without examining other options.
Step-by-step explanation:
A person is most likely to use heuristics when making a decision that is of relatively little importance and must be made quickly. This scenario corresponds to option b). Heuristics are cognitive shortcuts that simplify decision-making processes, especially when we face too much information, have limited time, the decision is unimportant, we have little information, or an appropriate heuristic comes to mind. For example, in voting, one might opt for a candidate from their preferred political party rather than analyzing every candidate's platform in depth. This decision would rely on a political party heuristic as a rule of thumb. Similarly, when deciding what to order at a restaurant, choosing the daily special without reviewing the entire menu is an application of a decision-making heuristic.
In contrast, when the decision is of great importance or when the person has time to explore different options, as in option c), the use of heuristics is less likely because more analytical and comprehensive methods for decision-making may be employed instead.
