Correct answer
C. They cause increased agricultural productivity
Step-by-step solution
Aerosols through their direct or indirect effects on plants can cause various problems in agriculture. However, a continuous increase in air pollution may represent a threat to agriculture in the future that is persistent and largely irreversible. Any type of air pollution negatively impacts agriculture, by causing climatic changes (reduces rainfall) as well as affecting the health of humans. Fog, mist, and dust are natural aerosols found in the air.
