Consider the following statements.
I. Extraction of metals from its ores is known as metallurgy.
II.Metallurgy includes only two operations i.e., reduction of metal oxide to metal and refining.
Select the correct statements.

Options

A. Only I
B. Only II
C. Both I and II
D. None of the above

Answer

To solve the question, let's analyze the two statements provided:

**Step 1: Evaluate the First Statement**
- The first statement claims that "extraction of metals from its ores is known as metallurgy."
- This statement is **correct**. Metallurgy is indeed the process through which metals are extracted from their ores.

**Step 2: Evaluate the Second Statement**
- The second statement claims that "metallurgy includes only two operations: reduction of metal oxide to metal and refining."
- This statement is **incorrect**. Metallurgy involves several steps, not just two. The main steps in metallurgy include:
1. **Enrichment or Dressing of Ore**: This is the process of increasing the concentration of the desired metal in the ore.
2. **Conversion of Enriched Ore to Metal Oxide**: This involves converting the concentrated ore into a metal oxide.
3. **Reduction of Metal Oxide to Metal**: This is the process of reducing the metal oxide to obtain the pure metal.
4. **Refining or Purification of Metal**: This step involves purifying the extracted metal to remove impurities.

**Step 3: Conclusion**
- Since the first statement is correct and the second statement is incorrect, the correct option to select is that **only the first statement is correct**.

**Final Answer:**
- The correct option is **Option 1: Only one**.
