Assertion(A):Hydrogen peroxide is kept in coloured bottles.
Reason (R):Hydrogen peroxide is a moderately reactive metal that can react with light or heat slowly to produce water.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true and R is not the correct explanation of A
C. A is true but R is false
D. A is false but R is true.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Hydrogen peroxide is kept in coloured bottles." This is true. Hydrogen peroxide is sensitive to light and can decompose when exposed to it, which is why it is stored in dark or colored containers to prevent light from catalyzing its decomposition.

2. **Understanding the Reason:**
- The reason provided is "Hydrogen peroxide is a moderately reactive metal that can react with light or heat slowly to produce water." This statement is incorrect. Hydrogen peroxide is not a metal; it is a chemical compound (H₂O₂) and is actually highly reactive, not moderately reactive. It decomposes into water (H₂O) and oxygen (O₂) when exposed to light or heat.

3. **Analyzing the Relationship Between Assertion and Reason:**
- The assertion is true, but the reason is false. The reason does not correctly explain why hydrogen peroxide is kept in colored bottles. Instead, it mischaracterizes hydrogen peroxide as a metal and incorrectly describes its reactivity.

4. **Conclusion:**
- Therefore, the correct option is that the assertion is true, but the reason is false.

**Final Answer:**
- Assertion (A) is true, and Reason (R) is false.
