What is a natural display of static electric discharge?

• A. Lightning
• B. Thunder
• C. Spark
• D. Current

Answer: (A)

The main idea is a visible, natural manifestation of static electricity. Lightning is the rapid, large-scale discharge of built-up electric charges in the atmosphere, so you see a bright flash across the sky as the electricity finds a path through the air. Thunder isn’t the discharge itself; it’s the sound produced when air is violently heated and expands by the energy of that same discharge. A spark is a smaller, localized discharge and can happen in nature, but lightning is the iconic, natural display of static electricity on a large scale. Current refers to the flow of electric charge, not a visible phenomenon.
