Aproblem-solving heuristic is
select one:
a. likely to be less effective than a strategy such as hill climbing or means-end analysis.
b. needed for unfamiliar problems but not for familiar problems.
c. a strategy that guides a search through the problem space.
d. guaranteed to find a problem solution if one exists.

Option C, a strategy that guides a search through the problem space, is the right answer.

Explanation:

The term heuristic is derived from the Greek word ‘eurisko’, which means to ‘find’, or to search. Therefore, it is an approach to find a solution to a problem. This method gives speed to the process of relinquishing a satisfactory resolution. In other terms, it is a strategy which is derived from the earlier encounters with similar problems. Such a strategy is dependent on using immediately accessible information to manage problem-solving in machines, humans and abstract issues.
