For a gas molecule, the mean kinetic energy $E$ is represented by $E = \frac{3}{2} k T$, with $T$ denoting the absolute (kelvin) temperature. What are the SI base units of $k$?
- A$\text{kg}^{-1}\,\text{m}^{-1}\,\text{s}^2\,\text{K}$
- B$\text{kg}^{-1}\,\text{m}^{-2}\,\text{s}^2\,\text{K}$
- C$\text{kg}\,\text{m}\,\text{s}^{-2}\,\text{K}^{-1}$
- D$\text{kg}\,\text{m}^2\,\text{s}^{-2}\,\text{K}^{-1}$
