Solution

The correct option is D $50^{o} C, 230^{o} C$
In the Mond's process, nickel is extracted and purified. Impure nickel reacts with carbon monoxide at $50 - 60^{o} C$ temperature and forms $N i (C O)_{4}$ leaving all the impurities, then $N i (C O)_{4}$ is heated to $220 - 250^{o} C$ to give pure nickel and carbon monoxide.
