Answer:
A. He felt he had spent enough time there.
Explanation:
In Walden, Thoreau tells us of his experiences living in the woods. He was interested in getting away from civilization in order to truly learn how to appreciate the things that are valuable in the world. He believed that solitude was going to be a positive influence in his life. Thoreau spent two years living in this way, and at the end of this period, he returned to civilization, feeling that he had spent enough time in the woods.
