Assertion (A): Sound is a form of energy that produces a sensation of ...
The Assertion statement is correct as sound is indeed a form of energy that leads to the sensation of hearing in our ears.
The Reason statement is also correct as it accurately describes sound waves as longitudinal waves where particles move parallel to the direction of wave propagation.
However, the Reason does not directly explain the Assertion, so the correct answer is Option B.

Assertion and Reason Overview
The Assertion (A) states that sound is a form of energy that produces a sensation of hearing in our ears. The Reason (R) explains that sound waves are longitudinal waves where individual particles of the medium move in a direction parallel to the direction of wave propagation.
Analysis of Assertion (A)
- Sound is indeed a form of energy.
- It requires a medium (solid, liquid, or gas) to travel.
- When sound waves reach our ears, they stimulate the auditory system, leading to the sensation of hearing.
Analysis of Reason (R)
- Sound waves are classified as longitudinal waves.
- In longitudinal waves, the displacement of the medium's particles is parallel to the direction of the wave's travel.
- This characteristic is crucial for understanding how sound propagates.
Connection Between A and R
- Both the Assertion and the Reason are true statements.
- While the Reason explains the nature of sound waves, it does not fully explain why sound produces a sensation of hearing.
- The sensation of hearing involves complex processes in the ear and brain, which are not covered by the explanation of sound waves alone.
Conclusion
- Since both statements are true but the Reason does not adequately explain the Assertion, the correct answer is option 'B': both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
