Solution

The correct option is C $S i O_{2} - A l_{2} O_{3}$
Ethane in presence of catalyst like $S i O_{2} - A l_{2} O_{3}$ and high pressure and temperature undergoes dehydrogenation to form ethene as a product. The reaction can be given as follow: $C H_{3} - C H_{3} S i O_{2} - A l_{2} O_{3} - ------- \to C H_{2} = C H_{2} + H_{2}$
