Answer:
Option (B) is correct.
Step-by-step explanation:
Marginal benefit refers to the benefit that a consumer can get from consuming an additional unit of a commodity.
If the marginal benefit is greater than the marginal cost then a consumer is continuing consuming the additional units of a commodity.
A consumer uses the marginal analysis for deciding whether to consume an extra unit of a commodity or not. In this analysis, a consumer compares the marginal benefit with the marginal cost.
