Answer : 3. "30000 deg Cent"

Answer: C) 30000 deg Cent Explanation: Lightning is extremely hot — a flash can heat the air around it to temperatures five times hotter than the sun’s surface. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash. Lightning heats the surrounding air to about 30,000 degrees Centigrades.
