Question:

$\text{Match List-I with List-II.}$ $\begin{array}{|c|c|} \hline \text{List-I} & \text{List-II} \\ \text{(Types of alloy)} & \text{(Composition)} \\ \hline \text{(A) Bronze} & \text{(I) Cu, Ni} \\ \text{(B) Brass} & \text{(II) Fe, Cr, Ni, C} \\ \text{(C) UK silver coin} & \text{(III) Cu, Zn} \\ \text{(D) Stainless Steel} & \text{(IV) Cu, Sn} \\ \hline \end{array}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $(A)-(IV), (B)-(III), (C)-(I), (D)-(II)$
2. $(A)-(IV), (B)-(II), (C)-(I), (D)-(III)$
3. $(A)-(III), (B)-(I), (C)-(IV), (D)-(II)$
4. $(A)-(III), (B)-(IV), (C)-(II), (D)-(I)$

Solution:

$\text{Hint: Bronze} \rightarrow \text{Cu, Sn}$ $\text{Brass} \rightarrow \text{Cu, Zn}$ $\text{UK silver coin} \rightarrow \text{Cu, Ni}$ $\text{Stainless steel} \rightarrow \text{Fe, Cr, Ni, C}$
