A parallel plate capacitor of capacitance $$C_1$$ with a dielectric slab in between its plates is connected to a battery. It has a potential difference $$V_1$$ across its plates. When the dielectric slab is removed, keeping the capacitor connected to the battery, the new capacitance and potential difference are $$C_2$$ and $$V_2$$ respectively, Then

A
$$V_1=V_2, C_1 < C_2$$
B
$$V_1 > V_2, C_1 > C_2$$
C
$$V_1 < V_2, C_1 > C_2$$
D
$$V_1=V_2, C_1 > C_2$$
