Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Absolute zero is a theoretically possible temperature at which the volume of the gas becomes zero. $P V = n R T$ . When $T = 0 K, V = 0$

The total kinetic energy of the molecule is zero at this temperature.
Total kinetic energy of the molecule is directly proportional to the temperature. When $T = 0 K$ , total kinetic energy $= 0$
Hence, both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
