Solution

The correct option is D Carbonyl
Nickel is purified by thermal decomposition of Nickel carbonyl compound, Ni(CO)4
First the impure nickel is heated upto a temperature of 5060oC which led to the formation of Ni(CO)4
Impure Ni+4CO5060oC−−−−Ni(CO)4250oC−−Ni+4CO
This process is known as Mond's Process.
