The correct answer is letter "C": Airlines because of instability.
Step-by-step explanation:
Decision-makers usually do not have enough information about environmental factors, so they have a hard time predicting external change.

In some cases, changes happen without man being able to foresee it. That is why of all the industries provided in the case, Airlines would be the most affected with their flights.
