Answer:
Answer is option B, i.e. Boredom.
Explanation:
Having mastered a particular task, there is high possibility that the person might not feel motivated enough to work more. This can be because he/she has already achieved the level of expertise in that specific job and now feels bored as the same job creates a sense of monotony to him/her. Therefore, the very possible natural consequence will be Boredom after one has gained mastery in his/her job.
