Two pendulum bobs, Bob A of mass \(m\) and Bob B of mass \(2m\), are suspended from light strings of equal length \(L\). Initially, the bobs are held at rest side-by-side at their lowest positions with a compressed, massless spring held between them. When the mechanism is released, the spring rapidly expands over a negligible time interval, pushing the bobs horizontally apart before falling away. Bob A and Bob B subsequently swing upward to maximum vertical heights \(h_A\) and \(h_B\) above their release position, respectively. Which of the following claims correctly compares the maximum heights \(h_A\) and \(h_B\), and provides the correct justification?
