Explanation:
Marginal cost refers to the addition to total cost when one more unit of output is produced. Marginal cost in the given case would refer to the additional cost incurred for reducing the current pollution level by one unit.
In the given case, a firm is charged $250 for each unit of pollution emitted under the pollution tax option.
