Answer:
A.dishonorable
Explanation:
In this excerpt Mandela talks of people hurting others for their own, selfish reasons. He calls their purposes, "ignoble", by the fact that he is talking badly of them we can assume that the word has a negative connotation. This means the answer must be A or C. Mandela does not say that these people are killing or physically harming anyone; instead, he points out how they are taking power from those who need it. This is not bloodthirsty; the word that better fits is dishonorable.
