Under which conditions is it most beneficial to use a heuristic approach to solve a problem?

C.

Explanation:

A heuristic approach is an approach to problem solving that focuses on using the most practical method to solve the problem, which may not always be the most optimal or perfect solution, but is enough to meet the goal. Therefore it can be said that the most beneficial condition for using a heuristic approach to solve a problem would be when the problem cannot be solved in a reasonable time and an approximate solution is acceptable.
