Electrostatics: JEE Main 2025 Physics question

A parallel plate capacitor is filled equally (half) with two dielectrics of dielectric constants $\varepsilon_1$ and $\varepsilon_2$, as shown in figures. The distance between the plates is d and area of each plate is A. If capacitance in first configuration and second configuration are $C_1$ and $C_2$ respectively, then $\dfrac{C_1}{C_2}$ is : First Configuration: the two dielectrics form two layers, each of thickness $d/2$, stacked between the plates. Second Configuration: the two dielectrics fill side-by-side halves of the plate area, each of full thickness $d$.
