The correct answer is C. A significant effect of the First Great Awakening was that it caused division among religious groups.
The First Great Awakening was a movement of Christian revitalization that spread through Protestant Europe and the American colonies in the 1730s and 1740s, leaving a permanent impact on American religion.
Christianity was carried to African slaves and it was a monumental event in New England that challenged established authority. It incited resentment and division among the old traditionalists, who insisted on the importance of continuing the ritual and doctrine, and the new drivers of rebirth, which encouraged emotional involvement and personal commitment. It had an important impact on the remodeling of the Congregational Church, the Presbyterian Church, the Dutch Reformed Church and the reformed German church and the strengthening of the Baptist and Methodist denominations. It had little impact between the Anglicans and Quakers.
