Answer

To solve the question regarding the benefits of national parks and wildlife sanctuaries as forms of in situ conservation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand In Situ Conservation**:
- In situ conservation refers to the conservation of species in their natural habitats. National parks and wildlife sanctuaries are examples of in situ conservation as they protect ecosystems and the species that inhabit them.

2. **Identify the Benefits of National Parks and Wildlife Sanctuaries**:
- **Benefit 1**: They help maintain the population of native species and subspecies.
- **Benefit 2**: They allow species to shift in response to environmental changes, promoting adaptation.
- **Benefit 3**: They conserve genetic diversity among species.

3. **Evaluate Each Option**:
- **Option 1**: "It can accommodate human-caused introduction of alien species."
- This is NOT a benefit. Introducing alien species can disrupt local ecosystems and threaten native species.
- **Option 2**: "It helps to maintain population of native species and subspecies."
- This is a benefit.
- **Option 3**: "It helps to make possible for species to shift in response to the environmental change."
- This is a benefit.
- **Option 4**: "It can conserve genetic diversity."
- This is a benefit.

4. **Conclusion**:
- The only option that does not represent a benefit of national parks and wildlife sanctuaries is **Option 1**. Therefore, the correct answer is **Option 1**.
