C. a → iii ,   b → v ,   c → i ,   d → iv

Step-by-step solution

Siderite is a mineral composed of iron (II) carbonate FeCO 3 . It is a widespread mineral that is an ore of iron. Calamine: Zinc ore is most commonly found as zinc carbonate ZnCO 3 known as calamine or smithsonite. Malachite -   CuCO 3 · Cu ( OH ) 2 , Malachite is a copper carbonate hydroxide mineral Cryolite -   Na 3 AlF 6 , which consists of Aluminium, Sodium & Fluorine.
