    B) I and II only

    C) I, III and IV

    D) Only

    Correct Answer: D

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}OH\xrightarrow[Oxidation]{[O]}C{{H}_{3}}COOH\] \[C{{H}_{3}}C{{H}_{2}}OH+C{{H}_{3}}COOH\xrightarrow{{}}C{{H}_{3}}COOC{{H}_{2}}C{{H}_{3}}\]\[2C{{H}_{3}}COOH+N{{a}_{2}}C{{O}_{3}}\xrightarrow{{}}2C{{H}_{3}}COONa\]\[+C{{O}_{2}}+{{H}_{2}}O\] \[C{{H}_{3}}C{{H}_{2}}C{{H}_{3}}+5{{O}_{2}}\xrightarrow{{}}3C{{O}_{2}}+4{{H}_{2}}O\]
