Assertion: For the extraction of iron, haematite ore is used. Reasion: Haematite is a carbonate ore of iron.

Options

A. Only the reasion is correct.
Both the assertion and reason are
B. correct, but the reason is not the correct explanation for the assertion. Both the assertion and reason are
C. correct and the reason is the correct explanation for the assertion.
D. Only the assertion correct .

Answer

To solve the assertion and reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Analyze the Assertion
- **Assertion**: "For the extraction of iron, haematite ore is used."
- **Explanation**: Haematite is indeed one of the primary ores used for extracting iron. The chemical formula for haematite is Fe2O3, which indicates that it is an iron oxide.

### Step 2: Analyze the Reason
- **Reason**: "Haematite is a carbonate ore of iron."
- **Explanation**: This statement is incorrect. Haematite is not a carbonate; it is an oxide of iron. Carbonate ores of iron include minerals like siderite (FeCO3), but haematite is specifically an iron oxide.

### Step 3: Conclusion
- Since the assertion is correct (haematite is used for iron extraction), but the reason is incorrect (haematite is not a carbonate ore, it is an oxide), we conclude that:
- The assertion is true.
- The reason is false.

### Final Answer
- The correct conclusion is that **only the assertion is correct**.
