Answer 1

Answer: (B)

A Ziegler-Natta catalyst, named after Karl Ziegler and Giulio Natta, is a catalyst used in the synthesis of polymers of 1-alkenes (alpha-olefins). The catalyst $TiCl _{3}$ is used for Ziegler - Natta polymerization.
The Wacker Oxidation is an industrial process, which allows the synthesis of ethanal from ethene by palladium-catalyzed oxidation with oxygen. The catalyst $PdCl _{2}$ is used for the Wacker process.
The Deacon process is a process used during the manufacture of alkalis (the initial end product was sodium carbonate) by the Leblanc process. The catalyst $CuCl _{2}$ is used for Deacon's process.
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. The catalyst $V_{2} O _{5}$ is used for the Contact process.
