The principle difference between point source and nonpoint source water pollution is a) whether the pollution is organic or inorganic b) the number of sources of pollution c) the amount of pollution d) whether it is from commercial or agricultural sources e) there is no difference, pollution is pollution

In this scenario, the best answer is B " the number of sources of pollution" is really the difference between point source and non-point source pollution.

A point source pollutant source is a single origin of pollution, such as from a factory chimney, a pipe, or an oil spill. A non-point source is caused by rain and snowmelt that mix together many pollutants from different point sources and spread this throughout the ecosystem.

The answer is B.) the number of sources of pollution
