Answer 1

Answer:

(I) - (c) ; (II) - (d) ; (iii) - (b)  ;  (Iv) - (a)

Explanation:

Minerals: The various compounds of metals which occur in the earth's crust and are obtained by mining are called minerals.

Ore: The minerals from which a metal can be profitably and easily extracted is called an ore .

All the ores are minerals but all minerals can not be ores.  

As we know that

Siderite => FeCO_{3}

Kaolinite => Al_{2}si_{2}O_{5} (OH)_{4}

Malachite => CuCO_{3}.Cu(OH)_{2}

Calamine => ZnCO_{3}
