 Option B

Explanation: A hedonic treadmill is a person's propensity to stay at a fairly stable level of comfort and happiness following a fortune shift or big goals being accomplished. As an individual earns more money, their aspirations and impulses grow in tandem, as per the hedonic treadmill model.

As a consequence, the increase in income does not result in a lasting improvement in satisfaction. The hedonic treadmill phenomenon states the often-held fact that wealthy individuals are just no happier than people living in poverty, and sometimes quite happy are those with serious financial problems.

Thus, from the above we can conclude that the correct option is B.
