The correct answer is B. The directory access control list should be updated to allow the user to have read and write. The ACL shows only the default owner/group permissions and “other” is read-only. Granting the specific user read/write via an ACL entry (e.g. setfacl -m u:user:rwX /mnt/data) gives them the needed access without making the directory world-writable or changing ownership.
