Correct answer

C. (a)→(iii),(b)→(v),(c)→(i),(d)→(iv)\left(a\right) \to \left(iii\right), \left(b\right) \to \left(v\right), \left(c\right) \to \left(i\right), \left(d\right) \to \left(iv\right)

Step-by-step solution

Siderite is a mineral composed of iron (II) carbonate FeCO3{FeCO}_{3}. It is a widespread mineral that is an ore of iron.

Calamine: Zinc ore is most commonly found as zinc carbonate ZnCO3{ZnCO}_{3} known as calamine or smithsonite.

Malachite −CuCO3⋅Cu(OH)2- {CuCO}_{3} \cdot Cu ( OH{)}_{2}, Malachite is a copper carbonate hydroxide mineral

Cryolite −Na3AlF6- {Na}_{3}{AlF}_{6}, which consists of Aluminium, Sodium & Fluorine.
