The accopmanying graph depicts the marginal social cost (MSC) and marginal social benet (MSB) of pollution emissions. Move the point, P, to the point representing the optimal level of pollution. What is the optimal quantity of pollution? The optimal quantity of pollution is not zero because: 0 the marginal social benet of pollution exceeds the marginal social cost of pollution at zero metric tons of pollution. O the marginal social cost of pollution equals the marginal social benet of pollution at zero metric tons of pollution. O the marginal social cost of pollution exceeds the marginal social benet of pollution at zero metric tons of pollution. Dollars 3 4 5 6 Metric tons of pollution 1"
