Solution

The correct option is D Pd/BaSO4

A catalyst used in Rosenmund reaction can be prepared by reduction of palladium(II) chloride solution in the presence of BaSO4

The Palladium Catalyst used in Rosenmund’s reduction must be poisoned with BaSO4 because the untreated catalyst Palladium(Pd) is too reactive and will undergo over reduction forming other products.
