D. Faraday

Explanation

To solve the question "Lightning was discovered by," we need to analyze the options provided and identify the correct answer based on historical context.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- Option 1: Ohm
- Option 2: Thomson
- Option 3: Franklin
- Option 4: Faraday

2. **Understand the Contributions of Each Scientist**:
- **Ohm**: Georg Simon Ohm is known for Ohm's Law, which relates voltage, current, and resistance (V = IR). He did not discover lightning.
- **Thomson**: J.J. Thomson is famous for discovering the electron and his work on cathode rays. He is not associated with the discovery of lightning.
- **Franklin**: Benjamin Franklin is well-known for his experiments with electricity and his famous kite experiment, which demonstrated the electrical nature of lightning. He is credited with discovering that lightning is a form of electricity.
- **Faraday**: Michael Faraday is known for his contributions to electromagnetism and electrochemistry, including the concept of electromagnetic induction. He did not discover lightning.

3. **Determine the Correct Answer**: Based on the contributions of each scientist, Benjamin Franklin (Option 3) is the one who is credited with the discovery of lightning as a form of electricity.

4. **Final Answer**: The correct answer is **Option 3: Franklin**.
