is used to detect the presence and kind of electric charge on anybody.

Options

A. Electroscope
B. Electric Generators
C. Van de Graff generator
D. Capacitors

Explanation

To solve the question regarding which device is used to detect the presence and kind of electric charge on a body, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a device that can detect both the presence and the type of electric charge (positive or negative) on an object.

2. **Reviewing the Options**: The options provided are:
- Electroscope
- Electric generators
- Van de Graaff generators
- Capacitors

3. **Analyzing Each Option**:
- **Electroscope**: This is a device specifically designed to detect electric charges. It consists of a metal rod connected to two thin metal leaves. When a charged object touches the rod, the charge is transferred to the leaves, causing them to repel each other if they have the same type of charge.
- **Electric Generators**: These are used to convert mechanical energy into electrical energy and do not detect charges.
- **Van de Graaff Generators**: These are used to generate high voltages and are not designed for detecting charges.
- **Capacitors**: These store electrical energy but do not detect the presence or type of charge.

4. **Conclusion**: Based on the analysis, the only device that can detect the presence and kind of electric charge is the **Electroscope**.

5. **Final Answer**: The correct answer is **Electroscope**.
