Units And Measurement And Dimensions

If $E$ and $E_0$ denote energies at time $t$ and $t_0$ respectively, and $L$ and $L_0$ distance from same point at $t$ and $t_0$ respectively, then which of the following equations can be declared to be incorrect on dimensional grounds?
(A) $E=\frac{2 E_0 L}{L_0}$
(B) $E=E_0 e^{-2 L / L_0}$
(C) $E=2 L e^{-L / E_0}$
(D) $E=2\left(E_0 / L_0\right) \times e^{-L / L_0}$
