• B. 0
• C. 273.15
• D. -100

Answer: (A)

Verified step by step guidance

1. Understand that absolute zero is the lowest possible temperature where particles have minimal thermal motion.
2. Recall that the Celsius temperature scale is based on the freezing point of water (0°C) and boiling point of water (100°C) at standard atmospheric pressure.
3. Know that absolute zero corresponds to 0 Kelvin (K) on the Kelvin temperature scale, which is an absolute thermodynamic temperature scale.
4. Use the conversion formula between Kelvin and Celsius: \(\text{Celsius} = \text{Kelvin} - 273.15\).
5. Apply this formula to absolute zero: \$0\,K - 273.15 = -273.15\,^{\circ}C$, which gives the value of absolute zero on the Celsius scale.
