Final answer:
The statement about underreward inequity being true when one's outcome/input ratio is lower than that of others is correct, reflecting the principles of equity theory.
Step-by-step explanation:
The statement that underreward inequity occurs when your outcome/input ratio is lower than the outcome/input ratio of a comparison other is true.
Equity theory posits that individuals gauge the fairness of their work rewards by comparing their own outcome/input ratio to that of others. Feeling underrewarded may occur when this ratio is lower for oneself than for someone else in a similar situation, which can lead to dissatisfaction and a sense of inequity.
