Answer

To solve the question "Pick up the correctly matched," we need to analyze the terms provided in the video transcript and identify the correct associations.

### Step-by-Step Solution:

1. **Identify Terms**: The terms mentioned in the transcript include:
- Water vascular system
- Kangaroo
- Merus pium (likely a misspelling or mispronunciation)
- Platyhelminthes (flatworms)
- Flame cells
- Earthworm

2. **Understand the Concepts**:
- **Water Vascular System**: This is a system found in echinoderms (like starfish), not in flatworms or earthworms.
- **Kangaroo**: This is a marsupial and does not relate to flatworms or the other terms mentioned.
- **Platyhelminthes**: This is the phylum that includes flatworms.
- **Flame Cells**: These are excretory structures found in flatworms (Platyhelminthes) and are responsible for excretion.
- **Earthworm**: Earthworms belong to the phylum Annelida, not Platyhelminthes.

3. **Match the Terms**:
- The correct match from the terms is **Flame Cells** with **Platyhelminthes**. Flame cells are indeed found in flatworms and are involved in excretion.

4. **Conclusion**: The correctly matched pair is **Flame Cells - Platyhelminthes**.

### Final Answer:
The correctly matched pair is **Flame Cells - Platyhelminthes**.
