C Correct answer
Explanation

Both commands use input redirection to feed the file content to the sort command. 'cat file | sort' pipes output, and 'sort < file' redirects input, but both result in the file being displayed in sorted order. Note: 'sort < cat < file' has invalid syntax but the question intends to show input redirection.
