The correct match between Item\(-I\) (starting material) and Item\(-II\) (reagent) for the preparation of benzaldehyde is : Item\(-I\)                                Item\(-II\)  \((I)\) Benzene                      \(( P )\) \(HCl\) and \(SnCl _{2}, H _{3} O ^{+}\) \((II)\) Benzonitrile                \((Q)\) \(H _{2}, Pd - BaSO _{4}, S\) and quinoline \((III)\) Benzoyl Chloride      \((R)\) \(CO , HCl\) and \(AlCl _{3}\)

1. A \(( I )-( Q ),( II )-( R )\) and \(( III )-( P )\)
2. B \(( I )-( R ),( II )-( Q )\) and \(( III )-( P )\)
3. C \(( I )-( R ),( II )-( P )\) and \(( III )-( Q )\)
4. D \(( I )-( P ),( II )-( Q )\) and \(( III )-( R )\)
