Options

A. Over - exploitation
B. Deforestation
C. Alien species invasion
D. More than one option is correct

Answer

To solve the question regarding the main cause of extinction of species from tropical areas, we can follow these steps:

### Step 1: Understand the Question
The question asks for the main cause of extinction of species specifically in tropical areas. This requires us to analyze the options provided.

### Step 2: Analyze Each Option
1. **Over-exploitation**: This refers to the excessive use of resources, which can lead to depletion. While it can contribute to extinction, it is not the primary cause in tropical areas.

2. **Deforestation**: This involves the clearing of forested areas, which leads to habitat destruction. Tropical areas are rich in biodiversity, and the loss of habitat is a significant factor in the extinction of species.

3. **Alien Species Invasion**: This refers to non-native species that are introduced into an ecosystem. While they can disrupt local ecosystems, they are not the primary cause of extinction in tropical areas.

4. **More than one option is correct**: This option suggests that multiple causes could be responsible for extinction. However, the question asks for the main cause.

### Step 3: Identify the Correct Answer
After analyzing the options, it becomes clear that **deforestation** is the most significant cause of extinction of species in tropical areas due to habitat destruction.

### Conclusion
The correct answer is **Deforestation** (Option 2).
