Why each option

Disabling SSID broadcasting prevents the access point from advertising its network name in beacon frames, making the network undiscoverable to users who do not already know it exists.

ADelete the wireless network

Deleting the wireless network removes it entirely, making it inaccessible to authorized users rather than simply hidden from discovery.

BRemove all passwords

Removing all passwords reduces security by allowing any user who discovers the SSID - hidden or not - to connect without authentication.

CLock all users

Locking user accounts prevents existing accounts from authenticating but does nothing to hide the network name from wireless scan results.

DDisable SSID broadcastingCorrect

When SSID broadcasting is disabled, the access point stops including the network name in its beacon frames, so the network does not appear in wireless scan results. Users who already know the SSID can still connect by manually entering it, satisfying both the undiscoverable and accessible-only-to-those-who-know-it requirements.
