Answer

To determine which snake has sensitive patches called pits that help it track down warm-blooded animals in the dark, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Key Features of the Snakes**: We need to understand the characteristics of the snakes listed in the options: Branded Krait, Cobra, Green Python, and Rattlesnake.

2. **Understand the Function of Pits**: The question specifies "sensitive patches called pits." These pits are specialized sensory organs that help certain snakes detect infrared radiation (heat) emitted by warm-blooded animals.

- **Cobra**: Cobras are also not known for having these pits; they rely on other senses for hunting.
- **Green Python**: While they are skilled hunters, they do not have the specialized pit organs.
- **Rattlesnake**: Rattlesnakes have specialized pits located between their eyes, which allow them to sense the heat from warm-blooded animals, even in complete darkness.

4. **Conclusion**: Based on the information gathered, the snake that has sensitive patches called pits for tracking warm-blooded animals in the dark is the **Rattlesnake**.

### Final Answer:
The correct answer is **Rattlesnake**.
