Options

A. Acoelomates
B. Deuterostomes
C. Protostomes
D. Enterocoelic

Answer

To answer the question of how to represent earthworms, insects, and snails with a single word, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Phylum of Each Organism**:
- Earthworm: Belongs to the phylum **Annelida**.
- Insect: Belongs to the phylum **Arthropoda**.
- Snail: Belongs to the phylum **Mollusca**.

2. **Understand the Classification**:
- All three organisms belong to different phyla, but they can be classified based on their embryonic development.

3. **Determine the Developmental Group**:
- The terms **Protostome** and **Deuterostome** are used to classify animals based on their embryonic development.
- Earthworms (Annelida), insects (Arthropoda), and snails (Mollusca) are all classified as **Protostomes**.

4. **Conclude with the Single Word**:
- Since earthworms, insects, and snails are all protostomes, the single word that can represent them collectively is **"Protostome"**.

### Final Answer:
**Protostome**
