A parallel plate capacitor is filled with $3$ dielectric materials of same thickness, as shown in the sketch. The dielectric constants are such that $k_3 > k_2 > k_1$. Let the magnitudes of the electric field in and potential drops across each dielectric be $E_3$, $E_2$,$ E_1$, $\Delta V_3$, $\Delta V_2$ and $\Delta V_1$, respectively. Which one of the following statement is true ?

$\mathrm{E} \times \frac{1}{\mathrm{k}} \Rightarrow \Delta \mathrm{V} \times \frac{1}{\mathrm{k}} \Rightarrow \mathrm{E}_{3}<\mathrm{E}_{2}<\mathrm{E}_{1}$
and $\Delta \mathrm{V}_{3}<\Delta \mathrm{V}_{2}<\Delta \mathrm{V}_{1}$
