Assertion :- Hooks and suckers are present in the parasitic form of flat worms.
Reason :- It helps in absorbing nutrients from the host body.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

To solve the question regarding the assertion and reason about parasitic flatworms, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Hooks and suckers are present in the parasitic form of flatworms."
- This statement is true. Parasitic flatworms, particularly those in the class Cestoda (like tapeworms), possess hooks and suckers that allow them to attach to the host's intestinal wall.

2. **Understanding the Reason**:
- The reason states that "It helps in absorbing nutrients from the host body."
- This statement is misleading. While hooks and suckers do allow the flatworms to attach to the host, the actual absorption of nutrients occurs through the body surface of the flatworm, not specifically through the hooks and suckers.

3. **Analyzing the Relationship**:
- The assertion is true, but the reason does not correctly explain the assertion. The hooks and suckers are for attachment, while nutrient absorption occurs through other means.

4. **Evaluating the Options**:
- Based on the analysis:
- Option 1: Both assertion and reason are true, and reason is the correct explanation of assertion - **Incorrect**.
- Option 2: Both assertion and reason are true, and reason is the incorrect explanation of assertion - **Incorrect**.
- Option 3: Assertion is true, and reason is false - **Correct**.
- Option 4: Assertion is false, and reason is false - **Incorrect**.

5. **Conclusion**:
- The correct answer is that the assertion is true, and the reason is false.

### Final Answer:
- The correct option is: **Assertion is true, and reason is false**.
