An electric dipole with dipole moment \(\vec{p}\) is placed in a uniform electric field \(\vec{E}\). The table lists four different orientations of the dipole, where \(\theta\) is the angle between \(\vec{p}\) and \(\vec{E}\).

Orientation	Angle \(\theta\)
1	\(30^\circ\)
2	\(90^\circ\)
3	\(150^\circ\)
4	\(180^\circ\)

Taking the electric potential energy of the dipole-field system to be zero when \(\theta = 90^\circ\), which of the following correctly ranks the orientations according to the electric potential energy \(U\) of the system, from greatest to least?
