    A)  \[\text{HN}{{\text{O}}_{\text{3}}}\text{,N}{{\text{H}}_{\text{4}}}\text{Cl,NO,}{{\text{N}}_{\text{2}}}\]

    B)  \[\text{HN}{{\text{O}}_{\text{3}}}\text{,NO,N}{{\text{H}}_{\text{4}}}\text{Cl,}{{\text{N}}_{\text{2}}}\]

    C)  \[\text{HN}{{\text{O}}_{\text{3}}}\text{,NO,}{{\text{N}}_{\text{2}}}\text{,N}{{\text{H}}_{\text{4}}}\text{Cl}\]

    D)  \[\text{N}{{\text{H}}_{\text{4}}}\text{Cl,}{{\text{N}}_{\text{2}}}\text{,NO,HN}{{\text{O}}_{\text{3}}}\]

    Correct Answer: C

    Solution :

    [c] \[\overset{+5}{\mathop{\text{HN}{{\text{O}}_{3}}}}\,,\overset{+2}{\mathop{\text{NO}}}\,,\overset{0}{\mathop{{{\text{N}}_{\text{2}}}}}\,,\overset{-3}{\mathop{\text{N}{{\text{H}}_{\text{4}}}\text{Cl}}}\,\]
    Hence, the correct option is [c]
