Answer

To solve the question "Terrestrial, poikilothermal animal with cleidoic eggs is," we need to analyze the characteristics of the options provided and identify which one fits the description.

### Step-by-Step Solution:

1. **Understanding Key Terms**:
- **Terrestrial**: Refers to animals that live on land.
- **Poikilothermal**: Refers to animals that are cold-blooded, meaning their body temperature varies with the environment.
- **Cleidoic eggs**: These are eggs that have a protective shell and are typically associated with reptiles and birds. They allow the embryo to develop in a terrestrial environment.

2. **Analyzing the Options**:
- **Option 1: Bufo (Toad)**: Toads are amphibians and typically lay soft eggs in water. They do not have cleidoic eggs, making this option incorrect.
- **Option 2: Columba livia (Pigeon)**: Pigeons are birds, which are warm-blooded (endothermic) and do not fit the poikilothermal description. Although they lay cleidoic eggs, this option is incorrect due to the temperature regulation aspect.
- **Option 3: Catla catla (Fish)**: This is a fish and not a terrestrial animal. Fish generally do not have cleidoic eggs. Thus, this option is incorrect.
- **Option 4: Pleurotus versicolor (Lizard)**: Lizards are reptiles, which are terrestrial, poikilothermal, and lay cleidoic eggs. This option fits all the criteria given in the question.

3. **Conclusion**:
- The correct answer is **Pleurotus versicolor (Lizard)**, as it is a terrestrial, poikilothermal animal that lays cleidoic eggs.

### Final Answer:
The terrestrial, poikilothermal animal with cleidoic eggs is **Pleurotus versicolor (Lizard)**.
