Explanation

On Linux, group membership changes in /etc/group take effect for a user only when a new login session is created. The kernel assigns the list of groups to a process at login time; running 'usermod -aG' updates the file but does not modify any currently active session's credentials. The user 'test' must log out and log back in (or use 'newgrp editors' as a workaround) to gain the new group membership in their session. Option B is incorrect - the file shows group write permission for 'editors'. Option C ('sudo source /etc/group') is not a valid or effective command for this purpose. Option D is incorrect because the editors group already has write permission on the file.
