Column-I gives certain situations in which capacitance of a capacitor is changed by different means. Column-II gives resulting effect under different conditions. Match the statements in column-I with the corresponding statements in column-II

Column-I Column-II
(A) The plates of a plane parallel plate capacitor are slowly pulled apart Then the magnitude of electric field intensity inside the capacitor (p) Increases if the capacitor is maintained at constant charge.
(B) The plates of a plane parallel plate capacitor are slowly pulled apart. Then the potential energy stored in the capacitor (q) Decreases if the capacitor is maintained at constant charge.
(C) The capacitance of an air filled plane parallel plate capacitor on insertion of dielectric. (r) Increases if the capacitor is  maintained at constant potential difference.
(D) A dielectric slab is inserted inside an air filled plane parallel plate capacitor. The potential energy stored in the capacitor. (s) Decreases if the capacitor is maintained at constant potential difference.
