  4. -373.15 °C

Correct answer and explanation

Correct answer: -273.15 °C

Explanation: ✅ Correct Answer: C) -273.15 °C 📚 Explanation: Absolute zero is the lowest possible theoretical temperature, at which the fundamental particles of nature have minimal vibrational motion and retain no heat energy. On the Kelvin scale, this is exactly 0 K, which translates to -273.15 degrees on the Celsius scale.
