Match List I with List II
Choose the correct answer from the options given below:
| LIST I | LIST II | |
|---|---|---|
| A. | Reverberatory furnace | I. Pig Iron |
| B. | Electrolytic cell | II. Aluminum |
| C. | Blast furnace | III. Silicon |
| D. | Zone Refining furnace | IV. Copper |
Choose the correct answer from the options given below:
- A.A-I, B-IV, C-II, D-III
- B.A-I, B-III, C-II, D-IV
- C.A-IV, B-II, C-I, D-III
- D.A-III, B-IV, C-I, D-II
Show answer and solution
Correct option: C
Solution
Reverberatory furnace is used in the extraction/refining of Copper (A-IV). Electrolytic reduction (Hall-Héroult process) is used to extract Aluminum from alumina (B-II). Blast furnace reduces iron ore to give Pig Iron (C-I). Zone refining is a purification technique used for semiconductors like Silicon (D-III). This gives A-IV, B-II, C-I, D-III, which is option 3.
