Three point charges are fixed at three corners of a square of side length \(d\): a charge \(+Q\) at the top-left corner, a charge \(+Q\) at the top-right corner, and a charge \(-Q\) at the bottom-left corner. Point \(X\) is at the empty bottom-right corner, Point \(Y\) is at the center of the square, and Point \(Z\) is at the midpoint of the left edge between \(+Q\) and \(-Q\). Assuming electric potential is zero at infinity, which of the following correctly ranks the electric potentials \(V_X\), \(V_Y\), and \(V_Z\) at these points?
