Answer :
Answer:
The correct answer is the letter b. the social benefit received by consumers is greater than the private benefit.
Explanation:
Externality occurs when the activity performed by one agent affects another agent, not reflecting on prices, and may be negative or positive. Positive externalities concern the benefits to a given agent caused by the influence of another agent's action. Thus, as there is a positive external benefit, the social benefit is greater than the private social benefit, generating less than the socially desirable amount produced.
