Options

A. forest loss
B. population explosion
C. air pollution
D. biodiversity losses

Explanation

**Step-by-Step Solution:**

1. **Understanding the Term "Evil Quartet":** The term "evil quartet" refers to a specific set of four major causes that contribute to the loss of biodiversity. It is a concept used to highlight the interconnectedness of these factors in threatening ecosystems and species.

2. **Identifying the Four Causes:**
- **Habitat Loss and Fragmentation:** This is the first cause, where natural habitats are destroyed or divided into smaller, isolated patches, making it difficult for species to survive and reproduce.
- **Overexploitation:** The second cause involves the unsustainable use of natural resources, such as overfishing, hunting, and logging, which depletes species populations.
- **Alien Species:** The introduction of non-native species (alien species) can disrupt local ecosystems, outcompete native species, and lead to declines in biodiversity.
- **Coextinction:** The fourth cause refers to the phenomenon where the extinction of one species leads to the extinction of another species that depends on it for survival.

3. **Conclusion:** The term "evil quartet" is directly related to these four major causes of biodiversity loss: habitat loss and fragmentation, overexploitation, alien species, and coextinction.

4. **Correct Answer:** The correct answer to the question is that "the evil quartet" is related to four major causes of **biodiversity loss**.
