Correct Answer: B
Solution :
\[{{V}_{2}}{{O}_{5}}\]is catalyst \[\to \]contact process for \[{{H}_{2}}S{{O}_{4}}\]\[TiC{{l}_{4}}/Al{{(Me)}_{3}}\to \] Ziegler Natta salt used as catalyst for polymerisation of ethene. \[PdC{{l}_{2}}\to \]used as catalyst for ethanal (Wacker process). Iron oxide \[\to \]is used as catalyst in Haber's synthesis.
