Three different configurations, labeled 1, 2, and 3, consist of four point charges fixed at the four vertices of identical squares of side length \(s\), as shown.

Configuration 1: Four charges of \(+q\) at the vertices.
Configuration 2: Charges of \(+q\), \(-q\), \(+q\), and \(-q\) arranged in alternating order around the perimeter.
Configuration 3: Charges of \(+q\), \(+q\), \(-q\), and \(-q\) arranged consecutively around the perimeter.

Which of the following correctly ranks the total electrostatic potential energy \(U\) of the three systems from greatest to least?
