The correct command to recursively make all files and sub-directories in a directory executable by all users is `chmod -R a+x progs`. However, the option provided in the question has a typo with `-r` instead of the correct `-R`. Despite this, option A is the closest to the correct syntax for achieving the described task. The correct flag for recursive operation is `-R`, and `a+x` adds execute permission for all users.
