(a)	Kernite	(i)	Tin
(b)	Cassiterite	(ii)	Boron
(c)	Calamine	(iii)	Fluorine
(d)	Cryolite	(iv)	Zinc

Choose the most appropriate answer from the options given below

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

Answer 1

Answer: (B)

Kernite $=N{a}_2{B}_4{O}_7\cdot 4H_{2}O$

Cassiterite $=Sn{O}_2$

Calamine $=ZnC{O}_3$

Cryolite $=N{a}_{3}A\ell F_6$
