Assertion : Inhabitants close to busy airports are likely to experience helth hazards.
Reason : Sound levels of jet aeroplanes usually excessd 160 dB.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion .
B. If both Assertion and Reason are true and The Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false .
D. If both Assertion and Reason are false .

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that inhabitants close to busy airports are likely to experience health hazards. This implies that living near airports can have negative effects on health.

2. **Analyzing the Reason**: The reason provided is that the sound levels of jet airplanes usually exceed 160 dB. This is a critical piece of information because it quantifies the noise level associated with jet airplanes.

3. **Linking Assertion and Reason**: To determine if the reason supports the assertion, we need to understand the implications of sound levels exceeding 160 dB. Sound levels above 120 dB are considered hazardous to human health. Since jet airplanes exceed this level, it logically follows that residents near airports may experience health issues due to this excessive noise.

4. **Conclusion**: Both the assertion and the reason are true. The reason provides a valid explanation for the assertion. Therefore, we conclude that the assertion is correct because the excessive noise from jet airplanes (exceeding 160 dB) can indeed lead to health hazards for nearby inhabitants.

5. **Final Answer**: The answer is A: Both the assertion and reason are true, and the reason is a correct explanation of the assertion.
