    B)  \[C{{H}_{3}}N{{O}_{2}}\]

    C) \[C{{H}_{3}}OH\]       

    D)  \[C{{H}_{3}}C{{H}_{2}}OH\]

    Correct Answer: C

    Solution :

    Nitrous acid converts \[-N{{H}_{2}}\] group of \[{{1}^{o}}\] aliphatic amines into \[-OH.\] Thus, \[C{{H}_{3}}N{{H}_{2}}+HN{{O}_{2}}\xrightarrow{{}}\underset{methanol}{\mathop{C{{H}_{3}}OH}}\,+{{N}_{2}}\uparrow +{{H}_{2}}O\]
