C Correct answer
Explanation

Journaling file systems like JFS and ext3/ext4 maintain an inode table to track file metadata and locations. The journal itself is a circular log that records changes before they're committed to the main file system. Options like 'mcells' and 'fragments' are not standard file system structures, while 'cylinder group' is specific to BSD Unix File System (UFS), not journaling file systems.
