Final answer:
The theme of power in 'The Three Questions' is best described as the king's realization that true power lies in being present and acting kindly in the moment, rather than controlling the future.
Step-by-step explanation:
The story "The Three Questions" by Leo Tolstoy explores the theme of power through the character of a king who seeks to understand the best time to do things, who are the right people to listen to, and the most important thing to do. The correct description of how the theme of power is developed in this story is Option 3: The king wants to have greater control over the future. He goes out in search of answers only to realize that his original wish was in vain. The king's journey demonstrates that true power comes from being present and doing good in the current moment, which is the most important time, with whoever happens to be with you, who are the most important people and doing good, which is the most important thing to do.
