$A$ parallel plate capacitor is filled with $3$ dielectric materials of the 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 $E_3, E_2, E_1$ and $\Delta V_3, \Delta V_2, \Delta V_1$,respectively. Which one of the following statements is true?

• A
  $E_3 < E_2 < E_1 \text{ and } \Delta V_3 < \Delta V_2 < \Delta V_1$
• B
  $E_3 > E_2 > E_1 \text{ and } \Delta V_3 > \Delta V_2 > \Delta V_1$
• C
  $E_3 < E_2 < E_1 \text{ and } \Delta V_3 > \Delta V_2 > \Delta V_1$
• D
  $E_3 > E_2 > E_1 \text{ and } \Delta V_3 < \Delta V_2 < \Delta V_1$
