The optimum level of pollution emissions:

A) is zero.
B) occurs where the marginal external benefit is zero.
C) occurs where no damage to the environment is being done.
D) occurs where the marginal external benefit equals the marginal external cost.
E) occurs where the marginal external cost equals the marginal cost of abatement.

Marginal External Benefit

Pollution Emissions
