Answer:
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.
