[A]: Tropical movements occuring in response to water stimulus are called Haptotropism.
[R]: Haptotropic movement occurs in response to vibrations

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Tropical movements occurring in response to water stimulus are called Haptotropism."
- **Analysis**: Haptotropism refers to movements in response to touch, not water. The correct term for movement towards or away from water is hydrotropism.

2. **Understanding the Reason**: The reason states that "Haptotropic movement occurs in response to vibrations."
- **Analysis**: This statement is also incorrect. Haptotropic movements are related to touch, not vibrations.

3. **Conclusion**: Since both the assertion and the reason are incorrect, we can conclude that the correct answer is that both statements are false.

4. **Final Answer**: Therefore, the correct option is that both the assertion and reason are false.
