Assertion : Waves produced by a motor boat sailing in water are both longitudinal and transverse in nature.
Reason : The longitudinal and transverse waves cannot be produced simultaneously.

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 the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "Waves produced by a motor boat sailing in water are both longitudinal and transverse in nature."

- When a motor boat moves through water, it creates waves.
- The motion of the boat pushes the water, creating compressions and rarefactions in the direction of the boat's movement. This is characteristic of longitudinal waves.
- Additionally, the boat also creates surface waves that move perpendicular to the direction of the boat, which are transverse waves.

**Conclusion for Step 1**: The assertion is true because both types of waves are produced.

### Step 2: Understand the Reason
The reason states that "The longitudinal and transverse waves cannot be produced simultaneously."

- This statement suggests that if one type of wave is being produced, the other cannot be present at the same time.
- However, as we analyzed in Step 1, both longitudinal and transverse waves can occur simultaneously when a motor boat moves through water.

**Conclusion for Step 2**: The reason is false because both types of waves can indeed be produced at the same time.

### Final Conclusion
- The assertion is true.
- The reason is false.

### Answer
The correct answer is that the assertion is true, and the reason is false.
