Final answer:
Directory files in Unix-like file systems typically contain file names and inode numbers. Inodes hold the file metadata, not the directory file itself. The correct answer to the question is 'File names & Inode Numbers'.
Step-by-step explanation:
The question refers to the contents of a directory file in a file system on a computer. In most traditional file systems, such as Unix and Unix-like systems, directory files contain file names and inode numbers. Inodes are data structures that store the metadata about a file, including the file size, permissions, owner, group, and pointers to the data blocks where the actual file contents reside. Therefore, the correct answer to the question is "B) File names & Inode Numbers", which corresponds to option 2 in the multiple-choice answers provided.
