Answer: The right answer is the C) Jackson's use of the word "benevolent" gives the passage a self-satisfied tone.
Explanation: Just to elaborate a little on the answer, it can be added that in this excerpt from President Andrew Jackson's message to Congress "On Indian Removal" (1830), the use of the word "benevolent" clearly gives it a tone of self-satisfaction, since the politician is describing the infamous removal of Indian tribes from their native territories as kindly and compassionate. By doing so, he is justifying and legitimizing the expulsion of the Indians from their states.
