A Parallel Plate Capacitor of Capacitance C0 Has Plates of Area

A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. While it is connected to the battery the space between the plates is filled with a material of dielectric constant 3. After the dielectric is added, the magnitude of the charge on the plates and the potential difference between them are what?

A) Q0, V0
B) Q0, V0
C) Q0, V0
D) 3Q0, V0
E) 3Q0, 3V0
