This setting is specifically designed to prevent Chrome OS devices from sleeping or shutting down
when they are not actively being used, but are on the sign-in screen. This is ideal for public
environments like libraries where the devices are meant to be accessible at all times.
Other options are incorrect because:
B: This setting controls wake locks, which are used to keep a device awake under certain conditions.
It doesn't directly control sleep behavior on the sign-in screen.
C: This setting controls how users can turn off the device, but doesn't prevent the device from
sleeping on its own.
D: This setting controls the maximum length of a guest session, but doesn't affect the device's sleep
behavior on the sign-in screen.
