Selected Answer: A
The command that will NOT update the modify timestamp on the file `/tmp/myfile.txt` is: A. `file /tmp/myfile.txt` The `file` command is used to determine the file type of a file and does not modify the contents of the file. Therefore, it does not affect the modify timestamp of the file. The other commands in the list, including the `echo`, `sed`, `touch`, and the second `echo` command, involve reading from, writing to, or modifying the file in some way, which can update the modify timestamp.
