Assertion : Bronze contains Sn (80%), Cu(10%) and Zn (10%).
Reason : Bronze get corroded in presence of air and water.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. IF both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that bronze contains 80% Sn (tin), 10% Cu (copper), and 10% Zn (zinc).
- This is incorrect because bronze is primarily an alloy of copper and tin, with typical compositions being around 90% copper and 10% tin. Zinc is not a major component of bronze.

2. **Understanding the Reason**:
- The reason provided states that bronze gets corroded in the presence of air and water.
- This statement is also incorrect. Bronze is known for its resistance to corrosion, especially compared to other metals. It does not easily corrode when exposed to air and water.

3. **Conclusion**:
- Since both the assertion and the reason are false, we can conclude that neither statement is correct.

4. **Final Answer**:
- Therefore, the correct option is that both the assertion and the reason are false.
