Which of these choices is an indirect cost of using coal?

A. Cost to transport coal

B. Cost of maintaining power plants

C. Cost to mine coal

D. Cost of pollution from burning coal

It's D or at least I think so. No one in the 1800s and 1900s gave much thought to that problem, but it is a serious limitation to using coal now. It makes an awful mess of the environment.

if you dont have cost of pollution from burning coal the answer is

Cost of damage to common resources
