Solution
The correct option is B Lightning, electric stream and UV radiation
Out of total nitrogen fixed by natural agencies, approximately 10% of this occurs due to physical processes such as lightning, thunderstorms, and atmospheric pollution. The lightning and ultra-violet radiations in the atmosphere favor combination of gaseous nitrogen and oxygen to form nitric oxide. the nitric oxides are again oxidized with oxygen to form nitrogen peroxide. The nitrogen peroxide can combine with water during rains to form nitrous acid and nitric acid. The acids fall on the ground along with rain water and react with alkaline radicals to produce water soluble nitrates and nitrites. The nitrates are soluble in water and are directly absorbed by the plants. Thus, the correct answer is option B.
