Out of different state parameters like `E, H, G, A` and S, only entropy(s) is the parameter whose absolute value can be determined, by using third law of thermodynamics. While perfect crystals hace zero entropy at `0K`, non-perfect crystals have some residual entropy at `0K`. From this info and the following data chart, answer the questions that follow :

What will be molar entropy of liquid R at `300 K`?

A

`150 J//K` mole

B

`145 J//K` mole

C

`45 J//K` mole

D

`50 J//K` mole
