The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Diode**: A diode is a semiconductor device that allows current to flow in one direction only. It consists of a p-n junction, where 'p' stands for positive (holes) and 'n' stands for negative (electrons). 2. **Biasing the Diode**: When a diode is connected to a battery, it can be biased in two ways: forward bias and reverse bias. This process of connecting a diode to a battery is known as biasing. 3. **Forward Bias Connection**: In forward bias, the anode (the positive side of the diode) is connected to the positive terminal of the battery, and the cathode (the negative side of the diode) is connected to the negative terminal of the battery. 4. **Reverse Bias Connection**: In contrast, in reverse bias, the anode is connected to the negative terminal, and the cathode is connected to the positive terminal of the battery. 5. **Identifying Anode and Cathode**: The circuit symbol of a diode helps identify the anode and cathode. The triangle part of the symbol indicates the anode, while the line at the opposite end indicates the cathode. 6. **Circuit Representation**: When representing a forward-biased diode in a circuit, it is important to show the correct connections: the anode connected to the positive terminal and the cathode connected to the negative terminal. Additionally, a small resistance may be included in the circuit for practical purposes. 7. **Choosing the Correct Option**: Based on the connections described, you can identify the correct option among the choices provided. The correct option will show the anode connected to the positive terminal and the cathode connected to the negative terminal.
