    B) \[C{{H}_{4}};{{H}_{2}}\]

    C) \[C{{H}_{4}};C{{H}_{3}}OH\]

    D) \[C{{H}_{3}}OH;CO\]

    Correct Answer: A

    Solution :

           Fischer-Tropsch process -                    \[\underset{\begin{smallmatrix}   \\   \end{smallmatrix}}{\mathop{\underbrace{CO+{{H}_{2}}}_{\text{Water}\,\text{gas}}}}\,+\underset{\text{Excess}}{\mathop{{{H}_{2}}}}\,\underset{\text{heat}}{\mathop{\xrightarrow{\text{CO}\,\text{or}\,\text{Ni}}}}\,\]\[\underset{\text{(Petrol)}}{\mathop{\text{Mixture}\,\text{of}\,\text{hydrocarbons}}}\,\,+{{H}_{2}}O\]
