Explanation
Hard disk data addressing assigns unique addresses to each physical block on the disk. A physical block (also called a sector) is the smallest addressable storage unit on a physical disk, traditionally 512 bytes, now often 4096 bytes (4K). Early addressing used CHS (Cylinder-Head-Sector), while modern drives use LBA (Logical Block Addressing), which maps each physical block to a sequential logical address. The other options are incorrect: 'logical block' is a file-system-level concept above the physical layer, and 'OS block' and 'hard disk block' are not standard terminology for this addressing concept.
