A dielectric slab of thickness `d` is inserted in a parallel plate capacitor whose negative plate is at `x=0` and positive plate is at `x = 3d`. The slab is equidistant from the plates. The capacitor is given some charge. As one goes from `0` to `3d(1998)`.

Options

A. Electric potential remains the same
B. Electric potential decreases continuously
C. Electric potential increases continuously
D. Electric potential increases first, then decreases and again increases
