D. American Indians gave the name to African American soldiers in the U.S. Army out of respect

Explanation:

Because, the African American were strong and helped to fight Indians in order to maintain peace. They were very strong and they faught like using the strength of the buffalo. so i believe that, this is when the american indians had given them that name.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
