According to general william t. sherman, what was the best answer to the "indian question"?

After the Civil War, America faced great change in many aspects - how the government functioned, the ending of slavery, and settlers moved west, thus developing those territories. Racial issues continued for the Native Americans though. There was debate on how to involve Native American groups into government and civilization in early America as well. This became known as the "Indian Question" (but really it was really more of a "what should we do with them" problem). 

People in government needed to decide how to handle these Native American groups. Many tribes did not want to be relocated, there had to be a determination on how reservations would be managed, and how Americans could "civilize" (live in homes, have formalized schooling, etc.) Native Americans. In 1865 General William T. Sherman chaired the Peace Commission, which proposed actions to be taken to solve America's "Indian Question". Their suggestion was to move Native Americans to separate areas, to be taught farming and prepare them for civilized life. This worked for a while, however, disagreements still continued between the groups. By 1883, Sherman's opinion changed to one with more drastic measures. He felt that utilizing the army could end the difficulties that they were having with Native Americans. The military would be able to use their power to dominate tribes that refused to relocate or if meetings became hateful. 

Ithink the answer should be a.
