The creative work that would have reflected typical American themes in the mid-1800s is option C, "A novel in which the hero moves to the woods and learns from the experience."
This description matches the plot of the classic American novel "Walden" by Henry David Thoreau, published in 1854. In the book, Thoreau moves to a cabin in the woods near Walden Pond and reflects on his experiences and observations of nature, society, and self-reliance.
During the mid-1800s, American literature often focused on themes of individualism, self-reliance, and the relationship between humans and nature. Thoreau's "Walden" is a prime example of this literary trend, which was part of a larger cultural and intellectual movement known as Transcendentalism.
