Assertion : Transverse waves travel through air in an organ pipe.
Reason : Air possesses only volume elasticity.

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 but re ason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true

Answer

To solve the assertion-reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Analyze the Assertion
**Assertion:** Transverse waves travel through air in an organ pipe.

- **Explanation:** In an organ pipe, sound is produced by the vibration of air columns. Sound waves are a type of mechanical wave that travels through a medium. There are two main types of mechanical waves: transverse waves and longitudinal waves.
- **Conclusion:** The assertion is **false** because sound waves in air are **longitudinal waves**, not transverse waves. In longitudinal waves, the particles of the medium move parallel to the direction of the wave propagation.

### Step 2: Analyze the Reason
**Reason:** Air possesses only volume elasticity.

- **Explanation:** Volume elasticity refers to the ability of a medium to change its volume under pressure. Air, being a gas, can compress and expand, which allows sound waves to propagate through it. This property is essential for the transmission of sound.
- **Conclusion:** The reason is **true** because air does indeed possess volume elasticity, which is necessary for the propagation of sound waves.

### Step 3: Conclusion
- Since the assertion is false and the reason is true, we can conclude that the correct relationship is that the assertion does not support the reason.

### Final Answer
The correct option is that the assertion is false, but the reason is true.
