The statement "Lightning is one of the natural mechanisms by which atmospheric nitrogen is converted to ammonia or ammonium ions" is definitely true. Thus, the correct option is B.
Lightning may be defined as the occurrence of a natural electrical discharge of a very short duration. The discharge of atmospheric electricity produces the flashing of light.
Lightning is one of the natural mechanisms that initiate the process of nitrogen fixation. Through this process, the atmospheric nitrogen (N2) is converted to ammonia (NH3) or ammonium ions (NH4+).
Therefore, it is well described above.
