    B)

    C) \[C{{H}_{3}}CH=CHC{{H}_{2}}C{{H}_{3}}\]

    D) \[\underset{\,\,\,\,\,C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C{{H}_{3}}-C-C{{H}_{3}}}}\,}}\,}}\,}}\,\]

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}-CH=CH-C{{H}_{2}}-C{{H}_{3}}\] it decolourizes \[KMn{{O}_{4}}\] solution because double bond is present.
