[A]: Root system in hydrophytes is poorly de- veloped.
[R]: The condition helps hydrophytes to avoid maximum water absorption

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 (A)**: The assertion states that "the root system in hydrophytes is poorly developed."
- **Explanation**: Hydrophytes are plants that thrive in aquatic environments. Their adaptation to such environments often leads to a reduced need for a well-developed root system since they are surrounded by water.

2. **Understanding the Reason (R)**: The reason states that "the condition helps hydrophytes to avoid maximum water absorption."
- **Explanation**: While it is true that hydrophytes do not need to absorb large amounts of water due to their aquatic environment, the reason provided does not accurately explain why their root systems are poorly developed.

3. **Analyzing the Relationship between A and R**:
- The assertion is true because hydrophytes generally have poorly developed root systems.
- However, the reason does not correctly explain the assertion. The poorly developed root system is not primarily to avoid maximum water absorption, but rather because they obtain nutrients and water directly from their environment without the need for extensive root systems.

4. **Conclusion**: Based on the analysis, the assertion is true, but the reason is not the correct explanation for the assertion. Therefore, the correct option is that the assertion is true, but the reason is false.

### Final Answer:
- Assertion (A) is true.
- Reason (R) is false.
- The correct option is that the assertion is true, but the reason is not the correct explanation.
