B. Turgor movement
C. Paratonic movement
D. Autonomic movement.

Answer

**Step-by-Step Solution:**

1. **Understanding the Pitcher Plant Structure**: The pitcher plant has a specialized structure that includes a modified leaf known as the pitcher, which has a lid. This lid plays a crucial role in trapping insects.

2. **Insect Attraction**: The lid of the pitcher plant is often brightly colored and produces nectar, which attracts insects. This is a key factor in the plant's ability to capture prey.

3. **Stimulus Response Mechanism**: When an insect lands on the lid of the pitcher plant, it stimulates the plant. This interaction is crucial as it triggers a response from the plant.

4. **Lid Closure**: The closure of the lid is a response to the presence of the insect. This movement is not spontaneous; it occurs due to the external stimulus provided by the insect.

5. **Identifying the Type of Movement**: The type of movement that occurs in response to an external stimulus is known as paratonic movement. In contrast, autonomic movement occurs due to internal factors without external stimuli.

6. **Conclusion**: Therefore, the closure of the lid in the pitcher plant is classified as a paratonic movement, which is the correct answer.

**Final Answer**: The closure of the lid in the Pitcher Plant is a paratonic movement.
