A capacitor is kept connected to the battery and a dielectric slab is inserted between the plates. During this process
  • A
    No work is done
  • B
    Work is done at the cost of the energy already stored in the capacitor before the slab is inserted
  • C
    Work is done at the cost of the battery
  • D
    Work is done at the cost of both the capacitor and the battery
