A Correct answer
Explanation

Correct answer. Wilkinson’s catalyst ([PH3P]3.Rh.Cl) is used in the hydrogenation of alkenes. Adam's catalyst (Pt/PtO) is used in various reduction reactions. Lazier catalyst (2CuO.Cr2O3) is an effective catalyst used for the reduction of aldehydes, ketones and esters to the corresponding alcohols, and aliphatic double bonds. Ziegler-Natta catalyst (TiCl4/Al(Et)3) is used in the synthesis of polymers of alpha-olefins.
