A student is demonstrating the transformation of kinetic and potential energy in a system using the pendulum shown below. At which point in this system does the pendulum bob demonstrate minimum potential energy? A. 1 B. 2 C. 3 D. 4

Without the image or further information, it is difficult to determine the specific points of the pendulum. However, if we assume that "1" is at the highest point of the swing and "4" is at the lowest point, then the pendulum bob would demonstrate minimum potential energy at point "4".
