Acid rain was an environmental hyperbole covering the effect of sulfur dioxide and nitrogen dioxide gasses being washed out of the atmosphere by rainfall. Downstream from coal-fired power generation and metal reduction processes, these gasses were part of the gas stack chemistry; sourced as minor constituents of the process coal. The pollutants were only measured in ppm quantities in major smoke stacks … famously I measured 200 ppm in the air from the Inco Superstack, measured over Toronto air space. Ontario has no coal plants or stacks left after environmentally forced decommissioning.
This would be A, herbicides is a chemical used by humans not plants!
