Final answer:
A permanent action is taken when it's feasible to eliminate the root cause of a problem, aiming to prevent recurrence and provide a lasting solution.
Step-by-step explanation:
When it is feasible to eliminate the root cause of a problem, the type of action that is taken is often referred to as a permanent action. This means that the solution is intended to resolve the issue once and for all, preventing it from recurring in the future. By addressing the underlying issue, rather than just treating symptoms or implementing temporary fixes, a permanent solution ensures that the problem does not arise again, thereby saving time and resources in the long run.
