### Step-by-Step Solution:

1. **Understanding Biosphere Reserves**: Biosphere reserves are areas designated to promote sustainable development and conservation of biodiversity. They are divided into different zones based on the level of human activity allowed.

2. **Identifying the Zones**: There are typically three main zones in a biosphere reserve:
- **Core Zone**: This is the innermost zone where no human activities are permitted. It is a legally protected area aimed at conserving biodiversity and natural resources.
- **Buffer Zone**: Surrounding the core zone, this area allows limited human activities such as research and education, but it is still primarily focused on conservation.
- **Transition Zone (Manipulation Zone)**: This is the outermost zone where human activities, including settlements and agriculture, are permitted.

3. **Answering the Question**: The question asks for the zone where no human activity is permitted. Based on the definitions:
- The **Core Zone** is the correct answer as it is the area specifically designated for conservation without human interference.

4. **Choosing the Correct Option**: Among the given options:
- A) Buffer Zone
- B) Core Zone
- C) Manipulation Zone
- D) None of these

The correct answer is **B) Core Zone**.

### Final Answer:
The zone of biosphere reserve where no human activity is permitted is known as the **Core Zone**.
