Answer:
B. change in total utility obtained by consuming one more unit of a good.
Explanation:
Marginal utility can be simply defined as the additional benefit, utility, or enjoyment, obtained from consuming one additional unit of a good. It can be estimated in monetary terms.
For example, if consuming one additional burger gives an additional marginal utility value at $5, and the burger costs $3, the consumer will likely buy the burger because the marginal utility is higher than the cost.
