A parallel plate capacitor is charged by a battery which is then disconnected. A dielectric slab is then inserted to fill the space between the plates. Match the changes that could occur with Column II.
| Column I | Column II |
| A. Charge on the capacitor plates | p. Decrease by a factor of K |
| B. Intensity of electric field | q. Increase by a factor of K |
| C. Energy stored | r. Remains same |
| D. Capacitance | s. None |
