Options:

A $8.31 \times 10^7 \mathrm{erg} \mathrm{K}^{-1} \mathrm{~mol}^{-1}$
B $8.31 \times 10^7$ dyne $\mathrm{cmK}^{-1} \mathrm{~mol}^{-1}$
C $8.31 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}$
D $8.31 \mathrm{~atm} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$

The correct answer is: $8.31 \mathrm{~atm} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$

$\left(\mathrm{atm} . \mathrm{K}^{-1} \mathrm{~mol}^{-1}\right)$ is not a unit of $R$
