Question

DEEPTHI GALAGALI · Accepted Answer

Final Answer : C, Explanation :  The marginal social cost (MSC) includes both the private costs incurred by producers and the external costs (such as air pollution) borne by society. Since producing plastic containers generates air pollutants, the MSC is higher than the private cost reflected in the supply curve. Therefore, the MSC curve is positioned above and to the left of the supply curve, indicating that the true cost of producing an additional unit is higher than what the market supply curve suggests.
