49. With reference to Black carbon, consider the following statements:
i) Black Carbon is produced due to incomplete combustion of biomass only.
ii) It absorbs solar radiation at all wavelengths.
iii) Deposition of black carbon on snow decreases albedo.
Options:

ii) It absorbs solar radiation at all wavelengths.
iii) Deposition of black carbon on snow decreases albedo.
Options:
The correct option is C c) ii and iii only
C) Explanation:
Black carbon (BC) is the most strong light absorbing component of particulate matter PM., and is formed by the incomplete combustion of fossil fuels, biofuels, and biomass.
BC can be defined specifically as a solid form of mostly pure carbon that absorbs solar radiation at all wavelengths.
BC absorbs both incoming and outgoing radiation of all wavelengths, which contributes to warming of the atmosphere and dimming at the surface
BC deposited on snow and ice darkens the surface and decreases reflectivity albedo., thereby increasing absorption and accelerating melting.
