Match the refining methods (column I) with metals (column II).
column I column II
(Refining methods) (metals)
(I) Liquation (a) Zr
(II) Zone refining (b) Ni
(III) Mond process (c)Sn
(IV) Van Arkel method (d) Ga
(a) (I) −(C); (II) −(a); (III) −(b); (IV) −(d)
(b) (I)−(b); (II) −(d); (III)−(a);(IV) −(c)
(c) (I) −(C); (II) −(d); (III) −(b); (IV) −(a)
(d) (I) −(b); (II) −(c); (III) −(d); (IV) −(a)

(II) Zone refining (b) Ni
(III) Mond process (c)Sn
(IV) Van Arkel method (d) Ga
(a) (I) −(C); (II) −(a); (III) −(b); (IV) −(d)
(b) (I)−(b); (II) −(d); (III)−(a);(IV) −(c)

(d) (I) −(b); (II) −(c); (III) −(d); (IV) −(a)
Mond’s process is used for refining of Ni, Van Arkel method for Zr, liquation is used for Sn and zone refining is used for Ga.
So, correct match is
(I) −(C); (II) −(d); (III) −(b); (IV) −(a)
