a

Explanation:

Nonpoint source pollution is defined as pollution that originates from many diffuse, scattered sources rather than a single, identifiable point. This wide variety of sources makes it hard to track and regulate, unlike point source pollution which has a clear origin. Option a describes point source pollution, option c is incorrect as nonpoint source pollution can change over time with factors like weather or land use.

Answer:

B. comes from a variety of sources
