There was no altruistic motive that prompted him to help her.

The correct answer is D. selfish.

Altruism is the principle or practice of unselfish concern for or devotion to the welfare of others. If there was no altruistic motive that prompted him to help her, then he did not help her out of a selfless concern for her welfare, but rather out of some other motive, such as self-interest.

Wicked, brutal, and inhuman are all words that describe someone who is cruel or violent. These words do not accurately describe the man in the question, as there is no indication that he was cruel or violent.

Selfish is the best answer because it accurately describes the man’s motivation. He helped her out of self-interest, not out of a selfless concern for her welfare.
