Why each option
In Data ONTAP, inodes are metadata structures that store file attributes and pointers to the actual data locations on storage.
Qtrees are logical partitions within a volume used for quota and export management and are directory-level constructs, not targets of inode pointers.
Inodes in Data ONTAP's active file system store file metadata and contain direct and indirect block pointers that reference the disk blocks where the actual file data physically resides. This is the standard UNIX-derived file system model ONTAP uses to map logical files to their physical storage locations on disk.
File segments is not the correct Data ONTAP terminology for the storage units that inodes point to - disk blocks is the accurate term.
Snapshot copies are managed through a separate copy-on-write block mapping mechanism and are not directly referenced by active file system inodes.
