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 evaluate the assertion and reason provided:

**Assertion (A):** Cuprite is concentrated by froth flotation process.
**Reason (R):** Cuprite is the sulphide ore.

### Step-by-step Solution:

1. **Identify the nature of Cuprite:**
- Cuprite is a mineral composed primarily of copper(I) oxide (Cu2O). It is classified as an oxide ore, not a sulphide ore.

2. **Evaluate the assertion:**
- The assertion states that cuprite is concentrated by the froth flotation process. Since cuprite is an oxide ore, this statement is **false**. Froth flotation is typically used for the concentration of sulphide ores, not oxide ores.

3. **Evaluate the reason:**
- The reason states that cuprite is a sulphide ore. This is also **false**, as cuprite is an oxide ore.

4. **Determine the relationship between assertion and reason:**
- Since both the assertion and the reason are false, the correct option would be that both statements are false.

5. **Select the correct answer:**
- Based on the evaluations, the correct option is **4** (both assertion and reason are false).

### Final Answer:
The answer is **4** (both assertion and reason are false).
