Answer options

  1. 0°C
  2. -100°C
  3. -273.15°C
  4. -32°C

Correct answer and explanation

Correct answer: -273.15°C

Explanation: ✅ Correct Answer: C) -273.15°C 📚 Explanation: Absolute zero is the lowest possible temperature where the fundamental particles of nature have minimum vibrational motion. It corresponds to 0 Kelvin on the thermodynamic temperature scale or -273.15°C on the Celsius scale. Reaching this temperature is theoretically impossible, though scientists have achieved fractions of a degree above it in laboratory settings.
