C Correct answer
Explanation

An inode (index node) is the fundamental data structure in UNIX filesystems that stores file metadata like permissions, ownership, size, location data, and timestamps. Each file has a unique inode number. The kernel and shell are not data structures, and filter is a different concept entirely.
