This question tests your knowledge of the common ores of some key metals. Let's break it down:
Step 1: Understanding the elements and their ores
- Al (P): Aluminum is most commonly extracted from bauxite, which is an ore rich in aluminum oxide. This ore is widely used in the extraction of aluminum through the Bayer process. Hence, P matches with 4 (Bauxite).
- Fe (Q): The primary ore for iron extraction is hematite. Hematite is an iron oxide mineral, and it is a major source of iron in the blast furnace method of extraction. Therefore, Q matches with 2 (Hematite).
- Ti (R): Rutile is the primary ore from which titanium is extracted. It is an oxide of titanium and is considered one of the most important sources of titanium metal. Hence, R matches with 1 (Rutile).
- Cu (S): Copper is primarily extracted from chalcopyrite, a copper iron sulfide mineral. It is the most significant copper ore in the world, and copper is extracted through processes like smelting. Thus, S matches with 3 (Chalcopyrite).
Step 2: Analyze the options
- Option (A): Incorrect — This option does not match the correct ores for each element. For instance, it incorrectly pairs Al with Rutile, which is the ore of Ti.
- Option (B): Incorrect — While Fe and Hematite are correctly matched, the other pairings are incorrect. Al is incorrectly matched with Hematite, and Cu is paired with Rutile, which is not correct.
- Option (C): Incorrect — While Fe and Hematite are correctly matched, this option incorrectly pairs Al with Chalcopyrite and Cu with Rutile.
- Option (D): Correct — This option matches Al with Bauxite, Fe with Hematite, Ti with Rutile, and Cu with Chalcopyrite, all of which are correct.
Step 3: Conclusion
The correct answer is Option (D), which correctly matches the elements in Column I with their respective ores in Column II. These pairings are well-known and commonly used in the extraction of these metals.
