  3. CA−-I, B−-III, C−-II, D−-IV
  4. DA−-III, B−-IV, C−-I, D−-II

Correct answer

A. A−-IV, B−-II, C−-I, D−-III

Step-by-step solution

Reverberatory furnace, in copper, tin, and nickel production, a furnace used for smelting or refining in which the fuel is not in direct contact with the ore but heats it by a flame blown over it from another chamber.Purification of aluminium by electrolytic refining is known as Hoope's process. By this process 99.9% pure aluminium metal is obtained.

The iron manufactured in Blast Furnaces contain about 3 – 4 % of Carbon and smaller quantities of many other impurities such as sulphur, Silicon, etc. This is called Pig Iron.

Zone refining is used for the purification of metals like Si, Ge, Ga which are used in semiconductors.
