Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
At absolute zero (minimum temperature) , motion of the molecules freezes , therefore they have only internal potential energy (as K=0) hence their energy (K+U) becomes minimum .Absolute zero 0K) is the lowest possible temperature hence at absolute zero , the temperature is minimum .Hence both, assertion and reason are correct and reason is a correct explanation of assertion .
