A: Cuprite is concentrated by froth floatation process
R: Cuprite is the sulphide ore.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step 1: Analyze the Assertion (A)
The assertion states: "Cuprite is concentrated by froth flotation process."
- **Understanding Cuprite**: Cuprite is a mineral with the chemical formula Cu2O. It is primarily an oxide of copper, not a sulphide.
- **Froth Flotation Process**: This method is typically used for concentrating sulphide ores, not oxide ores like cuprite.

**Conclusion for Assertion**: The assertion is incorrect because cuprite is not concentrated by the froth flotation process as it is an oxide ore.

### Step 2: Analyze the Reason (R)
The reason states: "Cuprite is the sulphide ore."
- **Understanding Ore Types**: Cuprite (Cu2O) is classified as an oxide ore, not a sulphide ore. Sulphide ores contain metal combined with sulfur, such as chalcopyrite (CuFeS2) or bornite (Cu5FeS4).

**Conclusion for Reason**: The reason is also incorrect because cuprite is not a sulphide ore; it is an oxide ore.

### Final Conclusion
Both the assertion and the reason are incorrect. Therefore, the correct answer would be option number 4, which states that both the assertion and reason are false.
