Options

A. Absence of legs
B. Presence of ventral nerve cord
C. Presence of malpighian tubules
D. They are hermaphrodite

Answer

To determine the trait common among Earthworm, Leech, and Centipede, we can analyze the given options:

1. **Absence of Legs**:
- Earthworms and leeches do not have legs, but centipedes do have legs. Therefore, this option is not common to all three.

2. **Presence of Ventral Nerve Cord**:
- All three organisms (Earthworm, Leech, and Centipede) possess a ventral nerve cord. This is a common trait among them, making this option a strong candidate.

3. **Presence of Malpighian Tubules**:
- Earthworms and leeches have nephridia for excretion, while centipedes have Malpighian tubules. Hence, this option is not common to all three.

4. **They are Hermaphrodites**:
- Earthworms and leeches are hermaphrodites, meaning they have both male and female reproductive organs. However, centipedes are not hermaphrodites. Therefore, this option is also not common to all three.

After analyzing all the options, the common trait among Earthworm, Leech, and Centipede is:

**Correct Answer: Presence of Ventral Nerve Cord.**
