A. Kelvin
B. Celsius
C. Centigrade
D. Fahrenheit
✅ The correct answer is option A.
Kelvin is the S.I. unit of temperature. The kelvin (symbolised as K) is the base unit of temperature in the International System of Units (SI). The Kelvin scale is an absolute thermodynamic temperature scale using as its point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
