Answer: Allocative efficiency is the situation whereby resources are allocated in such a way that the last unit of output that is produced provides a marginal benefit to consumers that is equal to the marginal cost of producing the product. (A)
Explanation:
Allocative efficiency is when production represents the preferences of consumer as every product is produced at the point where the last unit gives a marginal benefit to consumers that is equal to the marginal cost used in producing the product.
Allocative efficiency is the level of output that is achieved when the price of a good or service equates to the marginal cost of production. Allocative efficiency can be achieved when there is an optimal distribution in goods and/or services in response to the demand of consumers and when the marginal cost and the marginwl utility of the product or services are equal.
