Which of the following statements best describes the difference between black carbon and brown carbon?

Black carbon is formed primarily by the high temperature incomplete combustion of fossil fuels, while brown carbon is formed primarily by the combustion of organic matter.

Brown carbon is a type of particulate matter that absorbs sunlight and contributes to warming the Earth's surface, while black carbon is a type of organic aerosol that scatters sunlight and has a cooling effect on the atmosphere.

Black carbon is a type of organic carbon that is black in color, while brown carbon is a type of inorganic carbon that is brown in color.

None of the above

Explanation:

Black carbon is formed primarily by the high temperature incomplete combustion of fossil fuels, while brown carbon is formed primarily by the combustion of organic matter.
EXPLANATION:
Black carbon, or soot, is part of fine particulate air pollution (PM2.5) and contributes to climate change. Black carbon is formed by the incomplete combustion of fossil fuels, wood and other fuels. Complete combustion would turn all carbon in the fuel into carbon dioxide (CO2), but combustion is never complete, and CO2, carbon monoxide, volatile organic compounds, and organic carbon and black carbon particles are all formed in the process. The complex mixture of particulate matter resulting from incomplete combustion is often referred to as soot.
Brown carbon (BrC), a carbonaceous aerosol that absorbs solar radiation over a broad range of wavelengths, is beginning to be seen as an important contributor to global warming. It absorbs both inorganic and organic pollutants, leading to serious effects on human health. Atmospheric “Brown Carbon” (BrC) is a complex mixture of organic compounds with diverse compositions and variability of its light-absorbing properties. BrC formed by incomplete combustion of fossil fuels and biomass is an important contributor to the light absorption by atmospheric aerosols. So, Option (a) is correct.
