Question

Match List-I with List-II :

List-I	List-II
(a) Mercury	(i) Vapour phase refining
(b) Copper	(ii) Distillation refining
(c) Silicon	(iii) Electrolytic refining
(d) Nickel	(iv) Zone refining

Choose the most appropriate answer from the option given below .

• A. $\left(a\right)-\left(ii\right),\left(b\right)-\left(iv\right),\left(c\right)-\left(iii\right),\left(d\right)-\left(i\right)$
• B. $\left(a\right)-\left(ii\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(i\right),\left(d\right)-\left(iv\right)$
• C. $\left(a\right)-\left(i\right),\left(b\right)-\left(iv\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(iii\right)$
• D. $\left(a\right)-\left(ii\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(i\right)$

Answer 1

The correct option is D $\left(a\right)-\left(ii\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(i\right)$

Element	Refining method
Mercury	Distillation refining
Copper	Electrolytic refining
Silicon	Zone refining
Nickel	Vapour phase refining

So , option (d) is correct
