None of the above

Detailed explanation-1: -As lightning blasts through the atmosphere, it breaks apart nitrogen molecules. This allows them to combine with oxygen in the air to form nitrogen oxides. The rain dissolves these into nitrates, then carries them to Earth and into the soil.
Detailed explanation-2: -Bacteria play a key role in the nitrogen cycle. Some species of nitrogen-fixing bacteria are free-living in soil or water, while others are beneficial symbionts that live inside of plants.
Detailed explanation-3: -Lightning is another natural way. Nitrogen in the atmosphere can be transformed into a plant-usable form, a process called nitrogen fixation, by lightning. Each bolt of lightning carries electrical energy that is powerful enough to break the strong bonds of the nitrogen molecule in the atmosphere.
Detailed explanation-4: -A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and nitrogen dioxide, NO2. These forms of nitrogen then enter soils through rain or snow. Nitrogen can also be fixed through the industrial process that creates fertilizer.
