from the following combinations of physical constants (expressed through their as usual symbols) the only combination, that would have the same value in different systems of units, is:

Options

A. `(ch)/(2piepsilon_0^2)`
B. `(e^2)/(2piepsilon_0Gm_e^2`)(`m_e`=mass of electron)
C. `(mu_0epsilon_0G)/(c^2he^2)`
D. `(2pisqrt(mu_0epsilon_0))/(ce^2)h/G`
