શુદ્ધિકરણ પદ્ધતિ (સ્તંભ $I$) ને ધાતુ (સ્તંભ $II$) સાથે જોડો. 

સ્તંભ $I$  (શુદ્ધિકરણ પદ્ધતિ) સ્તંભ  $II$ (ધાતુઓ)
$(I)$ દ્રવગલન $(a)$ $Zr$
$(II)$ ઝોન શુદ્ધિકરણ  $(b)$ $Ni$
$(III)$ મોન્ડ પદ્ધતિ $(c)$ $Sn$
$(IV)$ વાન આર્કેલ પદ્ધતિ $(d)$ $Ga$

A

$(I) -(b); (II) -(c); (III) -(d); (IV) -(a)$

B

$(I) -(b); (II) -(d); (III) -(a); (IV) -(c)$

C

$(I) -(c); (II) -(a); (III) -(b); (IV) -(d)$

D

$(I) -(c); (II) -(d); (III) -(b); (IV) -(a)$
