Question

Match List-1 with List -II:
$\begin{array}{cc}\text{List-I}& \text{List-II}\\ \left(A\right)\text{Sphalerite}& \left(I\right)FeC{O}_3\\ \left(B\right)\text{Calamine}& \left(II\right)PbS\\ \left(C\right)\text{Galena}& \left(III\right)ZnC{O}_3\\ \left(D\right)\text{Siderite}& \left(IV\right)ZnS\end{array}$
Choose the most appropriate answer from the options given below:

• A. $\left(A\right)-\left(IV\right),\left(B\right)-\left(I\right),\left(C\right)-\left(II\right),\left(D\right)-\left(III\right)$
• B. $\left(A\right)-\left(III\right),\left(B\right)-\left(IV\right),\left(C\right)-\left(II\right),\left(D\right)-\left(I\right)$
• C. $\left(A\right)-\left(IV\right),\left(B\right)-\left(III\right),\left(C\right)-\left(II\right),\left(D\right)-\left(I\right)$
• D. $\left(A\right)-\left(II\right),\left(B\right)-\left(III\right),\left(C\right)-\left(I\right),\left(D\right)-\left(IV\right)$

Answer 1

The correct option is C $\left(A\right)-\left(IV\right),\left(B\right)-\left(III\right),\left(C\right)-\left(II\right),\left(D\right)-\left(I\right)$

Earth’s crust contains some naturally occurring components called minerals in which metal compounds are found. Ores can be said to be those minerals from which metal can be economically and easily extracted.


$\begin{array}{cc}\text{Ores}& \text{Formula}\\ \left(A\right)\text{Sphalerite}& \left(IV\right)ZnS\\ \left(B\right)\text{Calamine}& \left(III\right)ZnC{O}_3\\ \left(C\right)\text{Galena}& \left(II\right)PbS\\ \left(D\right)\text{Siderite}& \left(I\right)FeC{O}_3\end{array}$

Hence, the most appropriate option is (A).
