Correct option: B
ABCD(ii)(i)(iv)(iii)\begin{array}{cccccccccccccccccccc} \mathrm{A}&\mathrm{B}&\mathrm{C}&\mathrm{D}\\ {\mathrm{(ii)}}&{\mathrm{(i)}}&{\mathrm{(iv)}}&{\mathrm{(iii)}} \end{array}
Option B is correct because it correctly matches each ore with the element it contains: Kernite (Boron), Cassiterite (Tin), Calamine (Zinc), and Cryolite (Fluorine).
