Options

A. Legs in crabs
B. Tail of lizards
C. Viscera in holothurian echinoderms
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Autonomy**:
- Autonomy refers to the ability of an organism to lose a body part as a defense mechanism when threatened by a predator. This process allows the organism to escape while the predator is distracted by the detached body part.

2. **Identifying Examples of Autonomy**:
- The question provides several examples of organisms that exhibit autonomy:
- **Legs in Crabs**: Crabs can shed their legs when attacked, allowing them to escape.
- **Tail of Lizards**: Many lizards can drop their tails to evade predators, which can later regenerate.
- **Viscera in Holothurian Echinoderms**: Certain echinoderms, like sea cucumbers, can expel their internal organs as a defense mechanism.

3. **Analyzing the Options**:
- The question presents the options: legs in crabs, tail of lizards, viscera in echinoderms, and "all of the above."
- Each of the first three options is a valid example of autonomy.

4. **Conclusion**:
- Since all the examples listed in the options demonstrate the phenomenon of autonomy, the correct answer is "all of the above."

**Final Answer**: All of the above.
