Answer:
The correct answer is option D.
Explanation:
The law of diminishing marginal utility says that keeping other things constant, marginal utility derived from the consumption of a good will keep on declining with each additional unit consumed by the consumer.
The diminishing marginal utility is not applicable for comparison between two consumers or two goods. It is applied to consumption of a single good by an individual consumer.
The utility or satisfaction derived from a good is supposed to decline not increase with increase in quantity.
So, option D is the correct answer.
