Which of the following statements regarding temperature of an object in Kelvin scale is/are correct ?
1. It can be a negative, zero or positive quantity.
2. It can either be a negative or a positive quantity.
3. It can never be negative.
4. It can be a positive definite quantity.
Select the correct answer using the code given below :

The Kelvin scale is an absolute temperature scale where 0 K represents absolute zero, the theoretical point at which all classical molecular motion ceases. In classical thermodynamics, absolute zero is the lowest possible temperature; therefore, temperature on the Kelvin scale can never be negative (Statement 3). Furthermore, the Third Law of Thermodynamics implies that absolute zero is physically unreachable in a finite number of steps. Consequently, the temperature of any real physical object is always greater than zero, making it a positive definite quantity (Statement 4). Statements 1 and 2 are incorrect because they suggest the possibility of negative Kelvin temperatures, which are not possible for physical objects in standard thermodynamics. Thus, statements 3 and 4 are the correct descriptions.
