The region of the biosphere reserve, where human activity is restricted is :

Options

A. Restoration zone
B. Core zone
C. Buffer zone
D. Transition zone

Answer

To solve the question regarding the region of the biosphere reserve where human activity is restricted, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Biosphere Reserves**:
- Biosphere reserves are areas designated to promote sustainable development and conservation of biodiversity. They consist of different zones that have varying levels of human activity allowed.

2. **Identify the Zones of a Biosphere Reserve**:
- There are typically three main zones in a biosphere reserve:
- **Core Zone**: This is the innermost zone where human activity is strictly prohibited. It serves as a protected area for wildlife and ecosystems.
- **Buffer Zone**: Surrounding the core zone, this area allows for limited human activities that do not harm the environment. Activities may include research and education.
- **Transition Zone**: This is the outermost zone where human settlements and resource gathering are permitted. It is designed for sustainable use of resources.

3. **Determine the Zone with Restricted Human Activity**:
- From the definitions of the zones, the **Core Zone** is the area where human activity is completely restricted. This is the primary area for conservation efforts.

4. **Eliminate Incorrect Options**:
- The **Buffer Zone** allows limited human activity, and the **Transition Zone** permits human settlements and resource gathering. Therefore, these cannot be the correct answer.

5. **Conclude the Answer**:
- The correct answer to the question is the **Core Zone**, as it is the region of the biosphere reserve where human activity is restricted.

### Final Answer:
The region of the biosphere reserve where human activity is restricted is the **Core Zone**.
