C Correct answer
Explanation

The 'ls -ltr' command lists files in long format (-l), reverse (-r) and by modification time (-t). This combination shows the most recently modified files at the bottom, which is the standard Unix/Linux approach for viewing files with oldest first. The 'r' flag reverses the default order.
