A,C,D Correct answer
Explanation

chmod 700 gives owner rwx (read/write/execute) and no permissions to anyone else, satisfying the requirement. chmod 744 allows group/others to read the directory, and chmod 711 allows them to enter it (execute permission) - both violate 'except owner no one else should have access'. chmod 755 is a common permission but too permissive.
