The incorrect statement is

Options

A. Calamine and siderite are carbonates
B. Argentite and cuprite are oxides
C. Zinc blende and iron pyrites are sulphides
D. Malachite and azurite are ores of copper

Explanation

To solve the question of identifying the incorrect statement among the given options, we will analyze each option step by step.

### Step 1: Analyze Option A
- **Statement**: Calamine and Siderite are Carbonates.
- **Chemical Formulas**:
- Calamine: ZnCO3 (Zinc Carbonate)
- Siderite: FeCO3 (Iron Carbonate)
- **Conclusion**: This statement is correct because both calamine and siderite are indeed carbonates.

### Step 2: Analyze Option B
- **Statement**: Argentite is an Oxide.
- **Chemical Formulas**:
- Argentite: Ag2S (Silver Sulfide)
- Cuprite: Cu2O (Copper(I) Oxide)
- **Conclusion**: This statement is incorrect because argentite is not an oxide; it is a sulfide.

### Step 3: Analyze Option C
- **Statement**: Zinc blende and Iron pyrite are Sulfides.
- **Chemical Formulas**:
- Zinc blende: ZnS (Zinc Sulfide)
- Iron pyrite: FeS2 (Iron Disulfide)
- **Conclusion**: This statement is correct as both zinc blende and iron pyrite are sulfides.

### Step 4: Analyze Option D
- **Statement**: Malachite and Azurite are Ores of Copper.
- **Chemical Formulas**:
- Malachite: CuCO3·Cu(OH)2 (Copper Carbonate Hydroxide)
- Azurite: Cu3(CO3)2(OH)2 (Copper Carbonate Hydroxide)
- **Conclusion**: This statement is correct because both malachite and azurite are indeed ores of copper.

### Final Conclusion
After analyzing all the options, we find that:
- Option A: Correct
- Option B: Incorrect
- Option C: Correct
- Option D: Correct

Thus, the incorrect statement is **Option B**, which states that argentite is an oxide.

### Summary of the Solution
The answer to the question is **Option B**: Argentite is not an oxide.
