Answer:
According to rational-emotive behavior therapists, the source of much unhappiness is: <u>d. system of inappropriate beliefs.</u>
Explanation:
This type of therapy explains unhapiness by the beliefs a person has. It also states that a change in the belifs would change the sense of how a person feels.
