Options

A. Charging by friction
B. Charging by radiation
C. Charging by induction
D. Charging by conduction

Answer

To solve the question "What generates an electric charge on a conductor by bringing a charged object in contact with it?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**:
- When a charged object comes into contact with a neutral conductor, it transfers some of its charge to the conductor. This process is known as charging by conduction.

2. **Defining Charging by Conduction**:
- Charging by conduction occurs when a charged object touches a neutral object. The charged object can either be positively or negatively charged.

3. **Mechanism of Charge Transfer**:
- During contact, electrons (which carry a negative charge) will move from the charged object to the neutral conductor if the charged object is negatively charged. Conversely, if the charged object is positively charged, electrons from the neutral conductor will move to the charged object.

4. **Result of the Process**:
- After the contact, the neutral conductor becomes charged. The amount of charge it acquires depends on the charge of the object it was in contact with and the duration of the contact.

5. **Conclusion**:
- Therefore, the process that generates an electric charge on a conductor by bringing a charged object in contact with it is called **charging by conduction**.

### Final Answer:
The correct answer is **charging by conduction**.
