Explanation:

1. Lightning is a large-scale discharge of static electricity in nature, making it the most powerful display of this phenomenon.
2. An electroscope is a specialized device designed to detect static electric charge, unlike the other options which have unrelated functions.
3. Lightning rods work by providing a path for electrons (the charged particles involved in static discharge) to safely flow from a building to the sky, preventing damage.
4. Metals have free electrons that are not held tightly to their atoms, which is why they are good conductors, unlike the other insulating materials listed.

Answer:

1. b. Lightning
2. d. electroscope
3. c. electrons
4. d. metal
