Answer:
Option (2)
Step-by-step explanation:
The aerosol are defined as the suspended finer solid particles or very small drops of liquid that are present in air or gas.
These aerosols can affect the climate by changing the amount of heat that is penetrated into and eliminated from the atmosphere. They are light colored and have the ability to reflect the incoming solar radiations back into the atmosphere.
This aerosols can be naturally occurring or it can be anthropogenic. Some of the natural aerosols are dust and fogs, whereas, the anthropogenic aerosols includes smoke and haze.
This has both positive and negative impact on the climate, but overall, it can be considered that the presence of these aerosols helps in the cooling of the planet as it reflects more amount of heat into the space like the clouds.
Thus, the correct answer is option (2).
