The correct answer is option a: "a desire to retreat from society when necessary".
Explanation:
In the book "Walden" by transcendentalist Henry David Thoreau, the author describes his experience when he decided to built a one-room house at the quite place of Walden Pond. Thoreau found himself spiritually when he decided to have a simple life at natural surroundings, where he lived in for two years, two months, and two days. The attitude of Thoreau towards society was to find a place where he can retreat from it when necessary and have a peaceful life far from the city.
