A : TV signals are affected if a low flying aircraft passes by or a petrol vehicle is started next to it.
R : Aircraft signals or vehicle’s spark plug generate interfering EM waves.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To analyze the given statement, we will break it down into two parts: Assertion (A) and Reason (R).

**Step 1: Understanding the Assertion (A)**
The assertion states that TV signals are affected if a low-flying aircraft passes by or a petrol vehicle is started next to it. This indicates that external factors can disrupt the reception of TV signals.

**Step 2: Understanding the Reason (R)**
The reason provided states that aircraft signals or a vehicle’s spark plug generates interfering electromagnetic (EM) waves. This suggests that the interference caused by these EM waves is responsible for the disruption in TV signals.

**Step 3: Analyzing the Relationship**
To determine if the reason correctly explains the assertion, we need to understand how EM waves work. TV signals are transmitted as electromagnetic waves, and when additional EM waves are generated (like those from aircraft or vehicles), they can interfere with the original TV signals. This interference can lead to a degradation in the quality of the received signals.

**Step 4: Conclusion**
Since both the assertion and reason are correct, and the reason provides a valid explanation for the assertion, we can conclude that the answer is option 1: both A and R are correct, and R is the correct explanation of A.
