MB:

MB refers to the marginal benefits and when the consumer or the customer is willing to pay maximum price to the goods and services then it comes under marginal benefit. It is considered as the exchange unit which is used to acquire additional goods or services.

MOC:

MOC refers to the marginal opportunity cost which adds on to the business and the opportunities that the company provides to produce more goods. Marginal costs do not have any fixed costs and to calculate moc the total cost and the difference between the outputs of the two systems is calculated.

We are benefited only with MB and when MOC is considered there is a probability that can be benefited or cannot be benefited.
