Explanation

In UNISYS storage hierarchy, the order from largest to smallest is: POS (Physical Organizational Sector) > Track > Sector > Word. 1 POS = 64 tracks, 1 track = 28 sectors, and sectors contain words. This hierarchical structure organizes storage from the largest allocation unit (POS) down to the smallest (word). The other options incorrectly order these units.
