If the desire satisfaction theory is true, it is never good advice to tell someone to A. try to produce beautiful things. B. do what makes him happy. C. change all his desires. D. seek knowledge.

Option C, change all his desires, is the right answer.

Explanation:

The desire-satisfaction theory is an atonement theory. According to this theory, the well being of a person is the overall level of their desired satisfaction throughout their life. This theory states that something is good for a person only if satisfies that person's desires. In this way, if one gets what he wants makes him intrinsically better off.
