    Answer : Option A

    Explanation :

    Fixation converts nitrogen in the atmosphere into ammonium that plants can absorb through their root systems. 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.
