Which of the following reformers outlined the social gospel in a book entitled christianity and the social crisis? a. upton sinclair b. walter rauschenbusch c. jane addams d. ida tarbell

B. Walter Rauschenbusch

Rauschenbusch was a theologian who wrote Christianity and the Social Crisis in 1907, so that is the correct. Upton Sinclair was a muckraker, who wrote "the Jungle". Jane Addams was a suffragette and Ida Tarbell was another muckraker. So, A, C and D are not correct.
