Answer:
The correct answer is option B.
Explanation:
When a market is producing at its equilibrium price and quantity, the marginal benefit earned from the consumption will be equal to the marginal cost incurred in production.
The market at this level will achieve allocative efficiency. When the price of the product is equal to the marginal cost incurred in its production, the production is said to be allocatively efficient. The price represents a benefit to the consumers.
