a. lawn fertilizer runoff

Explanation: Lawn fertilizer runoff is a nonpoint source—diffuse and variable (depends on rainfall, many individual lawns), so it's hard to trace back to specific sources and regulate. Factories, waste treatment plants, and nuclear power plants are point sources that are easier to monitor and control.
