Explanation

systemctl restart networkd stops and then restarts the systemd-networkd service, causing it to re-read and apply the updated configuration files. This is the correct way to activate changes. Option B (enable) configures the service to start at boot but does not restart it now. Option C (status) only displays the current state of the service without changing anything. Option D (isolate) switches the entire system to a different systemd target (runlevel), which is a disruptive operation unrelated to simply reloading network settings.
