In the third step of the problem solving process, in which one generates a range of solutions, one should a. avoid ruling our or selecting a solution b. identify steps to implement the solution c. monitor the progress of a solution d. create a plan of action for the solution

 A. avoid ruling out or selecting a solution

In the problem-solving process, generating solution and implementing it is in different steps. When you are trying to find a solution, it is best to keep all alternative before rule it out. You can rule it out after taking some analyze it in the next process.

Your answer is going to be c.
