A rock at the edge of a 200-meter high cliff has less potential energy than an equal-sized rock at the edge of a 600-meter high cliff.

False, the potential energy is proportional to the height, therefore the rock at the edge of the 600m cliff would have three times more Ep than the one at the edge of the 200m cliff.

The statement that a rock at the edge of a 200-meter high cliff has less potential energy than an equal-sized rock at the edge of a 600-meter cliff is true. Potential energy is determined by the height of an object above a reference point, and a higher cliff means greater potential energy. Specifically, the potential energy increases proportionally with height according to the formula PE = mgh.
