Answer

To determine which pair of animals is similar based on the stated feature, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify which pair of animals shares a specific feature. The options provided are pairs of animals with a feature stated against them.

2. **Evaluate Option 1: Platypus and Kangaroo (VB Paris)**:
- **Definition**: VB Paris refers to animals that give birth to live young.
- **Analysis**:
- **Platypus**: This is an oviparous animal, meaning it lays eggs.
- **Kangaroo**: This is a viviparous animal, meaning it gives birth to live young.
- **Conclusion**: This pair is not correctly matched because the Platypus does not share the VB Paris feature.

3. **Evaluate Option 2: Turtle and Crocodile (Three-chambered heart)**:
- **Definition**: A three-chambered heart has three distinct chambers.
- **Analysis**:
- **Turtle**: Has a three-chambered heart.
- **Crocodile**: Has a four-chambered heart.
- **Conclusion**: This pair is not correctly matched because the crocodile does not have a three-chambered heart.

4. **Evaluate Option 3: Viper and Vulture (Cold-blooded)**:
- **Definition**: Cold-blooded animals are unable to regulate their body temperature internally.
- **Analysis**:
- **Viper**: This is a cold-blooded reptile (poikilothermic).
- **Vulture**: This is a warm-blooded bird (homeothermic).
- **Conclusion**: This pair is not correctly matched because the vulture is not cold-blooded.

5. **Evaluate Option 4: Crocodile and Camel (Direct development)**:
- **Definition**: Direct development means the young are born as smaller versions of adults without a larval stage.
- **Analysis**:
- **Crocodile**: Gives birth to young that are small versions of adults.
- **Camel**: Also gives birth to young that are small versions of adults.
- **Conclusion**: This pair is correctly matched because both animals exhibit direct development.

### Final Answer:
The correctly matched pair is **Option 4: Crocodile and Camel (Direct development)**.
