The answer is A. Charles Grandison Finney

Charles Grandison Finney is widely regarded as one of the most influential evangelists during the Second Great Awakening. He was a key figure in the revivalist movement, known for his innovative preaching style and his role in promoting social reforms such as abolitionism and women's rights. Finney's revivals and his emphasis on personal conversion and social activism had a significant impact on American religious life.

Ralph Waldo Emerson was a prominent American philosopher and essayist, known for his leadership in the Transcendentalist movement. While he was influential in American intellectual and cultural life, he was not primarily an evangelist and did not play a central role in the Second Great Awakening.

John L. O'Sullivan was a journalist and editor best known for coining the term "Manifest Destiny." He was not an evangelist and did not have a significant role in the religious revivals of the Second Great Awakening.

Joseph Smith was the founder of the Latter Day Saint movement, which led to the establishment of the Church of Jesus Christ of Latter-day Saints (Mormonism). While he was a religious leader during the same period, his influence was more specific to the development of the Mormon faith rather than the broader evangelical movement of the Second Great Awakening.
