Absolute zero is the theoretical lowest possible temperature where particles have minimal vibrational motion. The Celsius scale is related to the Kelvin scale by the formula $T(K) = T(°C) + 273.15$. Therefore, 0 K = $T(°C) + 273.15$, which gives $T(°C) = -273.15$. Among the given options, -273° Celsius is the closest value to absolute zero.
