Autotomy occurs in

Options

A. Cockroch
B. House Lizard
C. House Fly
D. Pigeon.

Answer

**Step-by-Step Solution:**

1. **Understanding Autotomy**: Autotomy is a biological phenomenon where an organism can intentionally shed a part of its body, usually as a defense mechanism against predators. This process allows the organism to escape while the predator is distracted by the detached body part.

2. **Identifying the Organisms**: The question provides four options: cockroach, house lizard, house fly, and pigeon. We need to determine which of these organisms is known for autotomy.

3. **Analyzing Each Option**:
- **Cockroach**: While cockroaches can lose legs, they do not have the ability to intentionally shed body parts as a defense mechanism.
- **House Lizard**: House lizards are known for their ability to perform autotomy, particularly with their tails. When threatened, they can detach their tail to escape from predators.
- **House Fly**: House flies do not exhibit autotomy; they have other means of escape.
- **Pigeon**: Pigeons do not have the capability of autotomy; they rely on flight to evade predators.

4. **Conclusion**: Based on the analysis, the organism that exhibits autotomy is the house lizard. This process involves the self-amputation of the tail when threatened, which can later regenerate.

5. **Final Answer**: Therefore, the correct answer to the question "Autotomy occurs in" is **house lizard** (option B).
