Answer: The correct answer is A- revivals.
Explanation: Church revivals are meetings usually held on consecutive nights to try and bring new people or converts to the church sponsoring the revival. The most notable revivals in modern times were held by Billy Graham, who held revivals at Madison Square Garden in New York from May 15, 1957 until September 1, 1957 and had over 2,000,000 people come to hear him preach.
