Answer:
A. Persuasion or surrender
Explanation:
When dealing with a difficult client one of two tactics are applied either Persuasion or Surrender. First, you would try to calmly but firmly explain the situation to your client and persuade them to follow your professional instructions and that you know exactly what you are doing, that the plan that you have presented is the best option going forward. If the persuasion is unsuccessful then the next best tactic would be to surrender the job and move on to the next client.
