Answer

To solve the question "Most of the poisonous snakes have:", we will analyze the options provided and determine which one correctly describes a characteristic of most poisonous snakes.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the common features of most poisonous snakes. We need to evaluate each option based on the anatomical characteristics of these snakes.

2. **Evaluate Option 1: Literally Compressed Tail**:
- This option suggests that poisonous snakes have a tail that is literally compressed.
- **Analysis**: Most poisonous snakes do not have a compressed tail; instead, they typically have a tail that is abruptly tapered. Therefore, this option is incorrect.

3. **Evaluate Option 2: Narrow Belly Scales**:
- This option states that poisonous snakes have narrow belly scales.
- **Analysis**: In reality, poisonous snakes are known to have broad belly scales, which aid in locomotion. Thus, this option is also incorrect.

4. **Evaluate Option 3: Small Uniform Belly Scales**:
- This option claims that poisonous snakes have small uniform belly scales.
- **Analysis**: This is inaccurate as well, since poisonous snakes typically possess broad belly scales rather than small uniform ones. Hence, this option is incorrect.

5. **Evaluate Option 4: Transverse Scales as Broad as Belly**:
- This option indicates that poisonous snakes have transverse scales that are broad like their belly scales.
- **Analysis**: This is correct. Many poisonous snakes do have broad transverse scales, which are similar in width to their belly scales.

6. **Conclusion**: After evaluating all the options, the correct answer is **Option 4: Transverse scales as broad as belly**.

### Final Answer:
Most of the poisonous snakes have transverse scales that are as broad as their belly scales.
