Answer

**Step-by-Step Solution:**

1. **Identify the Options**: The question provides four species to consider: Passenger Pigeon, Giant Panda, Bengal Tiger, and Black Rhino.

2. **Research Current Status**: To determine which species is at the highest risk of extinction, we need to look at the conservation status of each species.

3. **Evaluate Each Species**:
- **Passenger Pigeon**: This species is already extinct, so it cannot be at risk of extinction.
- **Giant Panda**: While once endangered, conservation efforts have improved their numbers, and they are now classified as "vulnerable."
- **Bengal Tiger**: This species is endangered but has seen some conservation success in recent years.
- **Black Rhino**: This species is critically endangered, primarily due to poaching for their horns and habitat loss.

4. **Determine the Highest Risk**: Among the options, the Black Rhino is critically endangered and faces significant threats from poaching and habitat loss, making it the species at the highest risk of extinction.

5. **Conclusion**: The correct answer is the Black Rhino, as it is currently at the highest risk of extinction among the listed species.
