    A)                 \[HCOOH+C{{O}_{2}}\] 

    B)                 \[C{{O}_{2}}+{{H}_{2}}O\]

    C)                 \[C{{O}_{2}}+CO+{{H}_{2}}O\]  

    D)                 \[HCOOH+CO\]

    Correct Answer: C

    Solution :

                    \[\begin{matrix}    COOH  \\    \overset{|\,}{\mathop{C}}\,OOH  \\ \end{matrix}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{{95}^{o}}C}CO+C{{O}_{2}}+{{H}_{2}}O\]
