A Linux administrator needs to grant a user named 'jane' write access to a file called 'data.log', which is currently only accessible by its owner 'john'. The file should not have its existing permissions altered for any other user or group. Which of the following commands would correctly grant 'jane' the required access?
chmod +w data.log
setfacl -m o:w data.log
setfacl -m u:jane:w data.log
setfacl -m u:jane:rwx data.log
chown jane data.log
chmod u+w data.log
