Earthworm is

Options

A. Ammonotelic
B. Ureotelic
C. Uricotelic
D. Ureotelic and ammonotelic

Explanation

### Step-by-Step Solution:

1. **Identify the Organism**: The question asks about the earthworm, which is an invertebrate organism belonging to the phylum Annelida.

2. **Understand Excretory Processes**: Earthworms have a specialized excretory system that utilizes structures called nephridia to remove waste products from their bodies.

3. **Determine Waste Products**: The waste products removed by earthworms primarily include ammonium ions and urea. This is due to their mode of respiration, which occurs through the skin (cutaneous respiration).

4. **Classify Excretion Types**:
- **Ammonotelic**: Organisms that excrete waste primarily in the form of ammonia (common in aquatic organisms).
- **Ureotelic**: Organisms that excrete waste primarily in the form of urea (common in terrestrial organisms).
- **Uricotelic**: Organisms that excrete waste primarily in the form of uric acid (also common in terrestrial organisms).

5. **Analyze Earthworm's Excretion**: Earthworms can excrete both ammonium ions and urea, indicating that they exhibit characteristics of both ammonotelic and ureotelic organisms.

6. **Select the Correct Answer**: Given the options provided, the correct classification for earthworms is that they are both ammonotelic and ureotelic, making the last option the correct answer.

### Final Answer:
Earthworm is **ureotelic and ammonotelic**.
