    C) Excess release of carbon-monoxide by incomplete combustion

    D) Excess formation of \[C{{O}_{2}}\] by combustion and animal respiration

    Correct Answer: A

    Solution :

    excess concentration of \[S{{O}_{2}}\] and \[N{{O}_{2}}\] in the atmosphere leads to acid rain after precipitation and \[S{{O}_{2}}\] converted into \[{{H}_{2}}S{{O}_{4}}\], while \[N{{O}_{2}}\] into \[HN{{O}_{3}}\].
