- A. They alter rainfall and monsoon patterns.
- B. They cause increased agricultural productivity.
- C. They have negative impact on agricultural land.
- D. They are harmful to human health.
Explanation
Aerosols are harmful environmental pollutants which have negative effects on agriculture. Aerosols can have several negative impacts on agricultural lands, affecting crop health, soil quality, and overall agricultural productivity. Aerosols, particularly those containing pollutants or toxic substances, can settle on crop surfaces. When aerosols are deposited on leaves or fruits, they can cause physical damage, reduce photosynthesis, and inhibit gas exchange, ultimately affecting crop yields and quality.
