D. tornaria

Answer

To answer the question about the larva of Hemichordata, we will analyze the options provided and identify the correct one step by step.

### Step 1: Understand the options
We have four options to consider:
1. Catpole
2. No place
3. Amoset
4. Tautneria

### Step 2: Analyze each option
- **Option A: Catpole**
- The term "catpole" refers to the larval stage of amphibians, such as frogs. Since Hemichordata is a separate phylum, this option is incorrect.

- **Option B: No place**
- "No place" refers to the larval stage found in brachiopods. Since brachiopods are different from Hemichordata, this option is also incorrect.

- **Option C: Amoset**
- The term "amoset" refers to the larval stage of lampreys, which are part of the phylum Chordata, not Hemichordata. Therefore, this option is incorrect as well.

- **Option D: Tautneria**
- "Tautneria" is identified as the planktonic larva of Hemichordata. This is the correct option because it directly relates to the larval stage of the Hemichordata phylum.

### Step 3: Conclusion
After analyzing all the options, we can conclude that the larva of Hemichordata is correctly identified as **Tautneria**.

### Final Answer:
The larva of Hemichordata is **Tautneria**.
