    D) which depends on the amount of dust in air

    Correct Answer: A

    Solution :

    During thunderstorm, there is formation of NO which changes to \[N{{O}_{2}}\] and ultimately to \[HN{{O}_{3}}\](acid-rain). \[{{N}_{2}}+{{O}_{2}}\xrightarrow{{}}NO\xrightarrow{{{O}_{2}}}N{{O}_{2}}\]                                                 \[\xrightarrow{{}}{{N}_{2}}{{O}_{5}}\xrightarrow{{{H}_{2}}O}HN{{O}_{3}}(pH<7)\]
