    \[\underset{n-hexane}{\mathop{C{{H}_{3}}{{(C{{H}_{2}})}_{4}}C{{H}_{3}}}}\,\xrightarrow{Anhy.AlC{{l}_{3}}/HCl}\]                \[\underset{2\text{-methyl}\,\,\text{pentane}}{\mathop{C{{H}_{3}}-\underset{\,C{{H}_{3}}}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-{{(C{{H}_{2}})}_{2}}}}\,-C{{H}_{3}}\]        \[+\underset{3\text{-}\,\text{methyl}\,\,\text{pentane}}{\mathop{C{{H}_{3}}C{{H}_{2}}-\underset{C{{H}_{3}}}{\mathop{\underset{\mathbf{|}}{\mathop{CH}}\,}}\,-C{{H}_{2}}-C{{H}_{3}}}}\,\] The above reaction is known as

    A)  aromatisation    

    B)        pyrolysis            

    C)         isomerization     

    D)         oxidation
