• D. $\left(a\right)\to \left(ii\right),\left(b\right)\to \left(i\right),\left(c\right)\to \left(iv\right),d\to \left(iii\right)$

Answer 1

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

$\text{Kernite}:N{a}_2{B}_4{O}_7.4H_{2}O\left(Boron\right)$

$\text{Cassiterite}:Sn{O}_2\left(Tin\right)$

$\text{Calamine}:ZnC{O}_3\left(Zinc\right)$

$\text{Cryolite}:N{a}_{3}Al{F}_6\left(Fluorine\right)$

$\left(a\right)-\left(ii\right),\left(b\right)-\left(i\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(iii\right)$
