D. All of these

Answer

To solve the question "Choose the correct statement," we will evaluate each of the given statements about lizards and snakes.

### Step-by-Step Solution:

1. **Evaluate the first statement: "Lizards show autotomy."**
- **Definition of Autotomy:** Autotomy is the ability of an organism to shed a body part, often as a defense mechanism against predators.
- **Application to Lizards:** Many lizards can indeed shed their tails when threatened, allowing them to escape while the predator is distracted by the detached tail.
- **Conclusion:** This statement is **correct**.

2. **Evaluate the second statement: "Most lizards are oviparous."**
- **Definition of Oviparous:** Oviparous animals lay eggs that develop and hatch outside the mother's body.
- **Application to Lizards:** Most lizards do reproduce by laying eggs, although some are viviparous (giving live birth). However, the majority of lizard species are indeed oviparous.
- **Conclusion:** This statement is **correct**.

3. **Evaluate the third statement: "Poison glands in snakes are modified parotid glands."**
- **Definition of Parotid Glands:** Parotid glands are a type of salivary gland.
- **Application to Snakes:** In many venomous snakes, the parotid glands have evolved to produce venom, which is used for subduing prey and defense.
- **Conclusion:** This statement is **correct**.

4. **Final Conclusion:** Since all three statements are correct, the answer to the question is that **all of the statements are correct**.
