C Correct answer
Explanation

The kernel uses the 'type' field in the file's inode to distinguish between ordinary files and device files. Each inode contains a type field that identifies whether the file is a regular file, directory, character device, block device, symbolic link, etc. Option A (temp field) and B (id field) don't exist for this purpose. Option D is wrong because the type is in the file's inode, not the directory's.
