(I, II, III, IV) provided in List – II and select the correct answer using the code given below the lists.
$\begin{array}{cc}P.Zn& 1.Self-reduction\\ Q.Cu& 2.Pyrometallurgy\\ R.Pb& 3.Bessemerisation\\ S.Fe\left(steel\right)& 4.Roasting\end{array}$

• A. P-2,3 , Q-1,2,4, R-1,2, S-1
• B. P-1,4 , Q-2,3, R-1,3, S-3,4
• C. P-2,4, Q-1,2,3,4, R-1,2,4, S-2,3,4
• D. P-1, Q,2,4, R-3, S-2,3,4

Answer 1

The correct option is C

P-2,4, Q-1,2,3,4, R-1,2,4, S-2,3,4

P. The metallurgy of Zn involves roasting and pyrometallurgy.
Q. The metallurgy of Cu involves all the given processes.
R. The metallurgy of Pb involves roasting, pyrometallurgy and self–reduction
S. In iron metallurgy we use roasting, bassemerisation and pyrometallurgy.
