Which of the following groups appears to be more vulnerable to extinction?

Options

A. Fishes
B. Amphibians
C. Birds
D. Mammals

Answer

To determine which group appears to be more vulnerable to extinction, we can analyze the provided information step by step.

### Step-by-Step Solution:

1. **Identify the Groups**: The question presents several groups of animals, including amphibians, mammals, birds, and fish.

2. **Examine the Percentage of Threat**: We need to look at the percentage of each group that is currently facing threats of extinction:
- Amphibians: 32% are at risk of extinction.
- Mammals: 23% are at risk of extinction.
- Birds: 12% are at risk of extinction.
- Fish: Very low risk of extinction (not specified but implied to be lower than the others).

3. **Compare the Percentages**: By comparing the percentages, we can see which group has the highest percentage of species at risk:
- Amphibians (32%) > Mammals (23%) > Birds (12%) > Fish (very low risk).

4. **Conclusion**: Since amphibians have the highest percentage of species facing extinction threats, they are the most vulnerable group among the options provided.

### Final Answer:
The group that appears to be more vulnerable to extinction is **amphibians**.
