Answer:
The correct answer is the option A: Nothing. Once you determine the root cause, your work is done whether it is in your control or not.
Explanation:
To begin with, the question is related to what is called "Root Cause Analysis" known in the management field as a process by which the managers tend to identify what cause a problem by looking deeply into the root of it thanks to an excesive analysis done by a team. It is necessesary to clarify that the main purpose of this method is just to identify the problems' root and from there to come out with solutions regarding the situation if able, but it is not the point of the analysis to take action or to implement those solutions. So therefore that if the situation turns to be out of the control of the person responsible for the analysis then there is nothing he could do because his job has already been done.
