A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates, which results in

  • A

    Reduction of charge on the plates and increase of potential difference across the plates

  • B

    Increase in the potential difference across the plates, reduction in stored energy, but no change in the charge on the plates.

  • C

    Decrease in the potential difference across the plates, reduction in stored energy, but no change in the charge on the plates

  • D

    None of the above
