__________that currently face the threat of becoming endangered in the near future.

Options

A. Vulnerable species
B. Endangered species
C. Critically-endangered species
D. Both (b) and (c)

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about species that are currently at risk of becoming endangered in the near future. This indicates a need to identify a specific category of species based on their population status.

2. **Identifying Categories of Species**: The International Union for Conservation of Nature (IUCN) classifies species based on their risk of extinction. The relevant categories include:
- Vulnerable Species
- Endangered Species
- Critically Endangered Species

3. **Defining Vulnerable Species**: Vulnerable species are those whose populations have declined significantly but are not yet classified as endangered. Specifically, vulnerable species have a population that is reduced by about 50%. This means that they still have a chance for recovery if conservation efforts are made.

4. **Defining Endangered and Critically Endangered Species**:
- Endangered species have seen a more severe decline, with populations reduced by about 80%.
- Critically endangered species are at the highest risk, with populations declining by 90% or more, making them extremely close to extinction.

5. **Conclusion**: Based on the definitions provided, the species that are currently facing the threat of becoming endangered in the near future are classified as **Vulnerable Species**. An example of a vulnerable species is the Giant Panda.

6. **Answering the Question**: Therefore, the correct answer to the question is "Vulnerable species."
