Question:
Identify the pair of metals which are refined by zone refining method?
Identify the pair of metals which are refined by zone refining method?
Show Hint
Zone refining is based on the principle that
\[
\boxed{\text{Impurities are more soluble in the molten state than in the solid state.}}
\]
It is commonly used for
\[
\boxed{\mathrm{Si,\ Ge,\ Ga,\ In}.}
\]

The Correct Option is C
Solution and Explanation
Step 1: Recall the metals purified by zone refining.
Zone refining is used for obtaining ultra-pure metals and semiconductors.
Common examples are
\[
\boxed{\mathrm{Ge,\ Si,\ Ga,\ In}.}
\]
Step 2: Choose the correct pair. Among the given options, only \[ \boxed{\mathrm{Ga,\ In}} \] are purified by zone refining. Hence, \[ \boxed{(C)} \] is the correct answer.
