Solution

The correct option is B $N_{2} \to N O \to N O_{2} \to N O_{3}$
Atmospheric fixation of nitrogen occurs in the following steps:

The enormous energy of lightning breaks nitrogen ( $N_{2}$ ) molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxide ( $N O$ ).

Nitrogen oxide is further oxidized to form nitrogen dioxide ( $N O_{2}$ ).

These dissolve in rain, forming nitrates ( $N O_{3}$ ), that are carried to the earth and used by plants.
