The African Methodist Episcopal Church was an African American offshoot of the Methodist Church founded by Richard Allen in the late 18th century. It was started because white congregants at St. George's Episcopal Church forced black congregants to sit in segregated seats in the balcony. The church was known for its abolitionist work and its efforts to abolish slavery. So B, C. and D are applicable for the work they participated in.
Walter white, Langston Hughes, Claude McKay, and James Weldon Johnson were all famous 1920 African American representatives of a prominent literary movement of the 1920s - Harlem Rennaissance.
An example of an organization that sprung from the Second Great Awakening was the "American Bible Society" which promoted Christian education throughout the US.
