Correct answer

A. Semiconducting metal is produced by zone refining method which is based on the principle that the impurities a

Step-by-step solution

Correct Option is : (A) Semiconducting metal is produced by zone refining method which is based on the principle that the impurities are more soluble in melt than in the solid state of metals.
