Novels and Poems

I don't have the OA for this but would like to know the answer.

A mixture of poems and short fiction, Jean Toomer’s Cane has been called one of the three best novels ever written by Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man.


a)Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

b)Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison

c)a Black American—including Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

d)a Black American—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

e)a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man


I personally thought C was the answer.
'a' is required. So elimiate a and b.Being is not prefered in GMAT, so eliminate D and E. Please let me know what you think is correct.
