# Two identical air-filled parallel-plate capacitors, 1 and 2, each have capacitance \(C_0\) and are initially charged to a potential difference \(V_0\). Capacitor 1 remains connected to the battery maintaining the constant potential difference \(V_0\), while Capacitor 2 is disconnected from its power source, leaving it electrically isolated. A slab of dielectric material with dielectric constant \(\kappa > 1\) is then fully inserted between the plates of each capacitor.

| | Stored Energy of Capacitor 1 | Potential Difference across Capacitor 2 | Stored Energy of Capacitor 2 |
|—|—|—|—|
| Row A | Increases | Decreases | Decreases |
| Row B | Increases | Decreases | Increases |
| Row C | Decreases | Remains the same | Decreases |
| Row D | Decreases | Remains the same | Increases |

Which row in the table correctly describes the resulting changes in the stored electric energy of Capacitor 1, the potential difference across Capacitor 2, and the stored electric energy of Capacitor 2?

Two identical air-filled parallel-plate capacitors, 1 and 2, each have capacitance \(C_0\) and are initially charged to a potential difference \(V_0\). Capacitor 1 remains connected to the battery maintaining the constant potential difference \(V_0\), while Capacitor 2 is disconnected from its power source, leaving it electrically isolated. A slab of dielectric material with dielectric constant \(\kappa > 1\) is then fully inserted between the plates of each capacitor.

| | Stored Energy of Capacitor 1 | Potential Difference across Capacitor 2 | Stored Energy of Capacitor 2 |
|---|---|---|---|
| Row A | Increases | Decreases | Decreases |
| Row B | Increases | Decreases | Increases |
| Row C | Decreases | Remains the same | Decreases |
| Row D | Decreases | Remains the same | Increases |

Which row in the table correctly describes the resulting changes in the stored electric energy of Capacitor 1, the potential difference across Capacitor 2, and the stored electric energy of Capacitor 2?

- **A.** Row A
- **B.** Row B
- **C.** Row C
- **D.** Row D
