I. Changes far out in the planning horizon can indeed be made with little or no cost because plans have not yet been solidified, allowing for adjustments without significant impact. II. In the "frozen zone," resources are indeed committed, making changes difficult or costly as production schedules are set and materials are allocated. III is incorrect because changes in the near future are typically more costly due to the commitments and adjustments that need to be made in a shorter timeframe.
