Match the refining methods (Column I) with metals (Column II). Column I (Refining methods): (I) Liquation, (II) Zone Refining, (III) Mond Process, (IV) Van Arkel Method Column II (Metals): (a) Zr, (b) Ni, (c) Sn, (d) Ga

1. (I)-(c); (II)-(a); (III)-(b); (IV)-(d)
2. (I)-(c); (II)-(d); (III)-(b); (IV)-(a)
3. (I)-(b); (II)-(d); (III)-(a); (IV)-(c)
4. (I)-(b); (II)-(c); (III)-(d); (IV)-(a)

Correct answer: (I)-(b); (II)-(d); (III)-(a); (IV)-(c)

Solution

The correct option matches each refining method with the appropriate metal based on their specific refining processes: Liquation is used for tin (Sn), Zone Refining is effective for gallium (Ga), the Mond Process is specifically for nickel (Ni), and the Van Arkel Method is used for zirconium (Zr).
