Solution

The correct option is B Reducing photosynthesis
Aerosols are minute particles suspended in the atmosphere and are known to reduce primary productivity on earth. scattering and absorption of sunlight by anthropogenic aerosols reduce photosynthetically active radiation, (PAR) incident upon the Earth’s surface, but increase the fraction of the PAR that is diffuse.
So the correct answer is 'Reducing photosynthesis'.
