A parallel-plate capacitor with vacuum between its plates has plate area \(A\), plate separation \(d\), and free surface charge density of magnitude \(\sigma_0\) on each plate. The capacitor is disconnected from the charging source, and an uncharged dielectric slab of dielectric constant \(\kappa > 1\) is inserted to completely fill the space between the plates.

	Net Electric Field \(E\)	Induced Surface Charge Density \(\sigma_{\text{ind}}\)	Stored Electrostatic Energy \(U\)
(A)	\(\dfrac{E_0}{\kappa}\)	\(\sigma_0\left(1 - \dfrac{1}{\kappa}\right)\)	\(\dfrac{U_0}{\kappa}\)
(B)	\(\dfrac{E_0}{\kappa}\)	\(\dfrac{\sigma_0}{\kappa}\)	\(\dfrac{U_0}{\kappa}\)
(C)	\(\dfrac{E_0}{\kappa}\)	\(\sigma_0\left(1 - \dfrac{1}{\kappa}\right)\)	\(\kappa U_0\)
(D)	\(E_0\)	\(\sigma_0(\kappa - 1)\)	\(U_0\)

Which row in the table correctly compares the resulting net electric field magnitude \(E\), the induced surface charge density magnitude \(\sigma_{\text{ind}}\) on the dielectric faces, and the stored electrostatic energy \(U\) to their initial values \(E_0\), \(\sigma_0\), and \(U_0\)?
