Twelve identical resistors, each with resistance \(R\), are connected to form the edges of a cube. A total current \(I\) enters the network at vertex \(A\) and exits at the diagonally opposite vertex \(B\). Which of the following correctly pairs the equivalent resistance \(R_{\text{eq}}\) between vertices \(A\) and \(B\) with the current \(I_{\text{central}}\) flowing through each of the six central edge resistors located between the two intermediate sets of equipotential nodes?
