Answer:

Solution:

Zinc sulfide ore (ZnS – Zinc blende) is first converted into ZnO by roasting:

$2 Z n S + 3 O_{2} \to 2 Z n O + 2 S O_{2}$

ZnO is reduced by carbon (coke) on heating:

$Z n O + C \to Z n + CO$

Zinc vapors and carbon monoxide gas are produced; on cooling, zinc condenses as impure metal.

Therefore, X = ZnS, Y = Zn, Z = CO.

Correct option: (B) ZnS, Zn, CO
