The correct answer is: B. the satisfaction derived from each additional unit of a good consumed will decrease.
The law of diminishing marginal utility states that as a consumer acquires more of a good, the marginal utility, or satisfaction, derived from each additional unit of the good decreases. In other words, the first unit of a good will provide the consumer with the most satisfaction, the second unit will provide less satisfaction, and so on.
This is because as a consumer acquires more of a good, they become less and less hungry for it. For example, if you are very hungry, the first bite of food you eat will provide you with a lot of satisfaction. However, after you have eaten a few bites, you will become less hungry, and each additional bite will provide you with less satisfaction.
The law of diminishing marginal utility is a fundamental concept in economics, and it has a number of important implications. For example, it implies that consumers will not continue to consume a good indefinitely, even if it is free. This is because the satisfaction derived from each additional unit of the good will eventually decrease to the point where it is not worth the cost of acquiring the good.
The law of diminishing marginal utility also implies that consumers will be willing to pay more for the first unit of a good than they will be willing to pay for the second unit, and so on. This is because the first unit of a good provides the consumer with the most satisfaction, and the marginal utility of each additional unit decreases.
The law of diminishing marginal utility is a powerful tool that can be used to understand consumer behavior. It is a fundamental concept in economics, and it has a number of important implications.
