Marginal utility refers to the additional satisfaction or utility that a person receives from consuming an additional unit of a good or service. Initially, as one starts to consume food from a buffet, the marginal utility is positive and high because each additional bite is more satisfying when you are hungry. However, as one continues to eat more and more, the additional satisfaction from each extra bite starts to decrease. Eventually, it can reach a point where consuming more actually makes one feel worse, such as feeling uncomfortably full or even sick, which means the marginal utility becomes negative. This is why the correct answer is that marginal utility may become negative.
