Assertion: Circuit containing capacitors should be handled cautiously even when there is no current.
Reason: The capacitors are very delicate and so quickly break down.

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 correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer

To analyze the given assertion and reason, we will break down the concepts involved and provide a step-by-step explanation.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that circuits containing capacitors should be handled cautiously even when there is no current. This is true because capacitors can retain charge even after the power source is removed.

2. **Understanding the Reason**:
- The reason provided is that capacitors are very delicate and can quickly break down. While it is true that capacitors can be damaged if mishandled, the primary concern regarding safety is not about their delicacy but about the charge they may still hold.

3. **Capacitor Charging and Discharging**:
- When a capacitor is charged, it stores electrical energy in the form of an electric field. After disconnecting the power source (like a battery), the capacitor can still hold this charge for some time, depending on the circuit configuration and the capacitor's properties.

4. **Potential Danger**:
- If someone touches a charged capacitor, they may receive an electric shock due to the stored charge. This is the reason why caution is necessary when handling capacitors, even if the circuit appears to be inactive (no current flowing).

5. **Evaluating the Assertion and Reason**:
- The assertion is true: Capacitors should be handled with care even when there is no current.
- The reason is false: While capacitors can be delicate, the real concern is the charge they may hold, not their fragility.

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

### Final Answer:
- The assertion is true, and the reason is false.
