Why each option

Disabling SSID broadcasting prevents the wireless network name from appearing in passive scans, making it undiscoverable to users who do not already know it.

ADelete the wireless network

Deleting the wireless network removes access entirely for all users including authorized ones, rather than simply restricting discoverability.

BRemove all passwords

Removing all passwords reduces security by allowing any user who discovers the network to connect freely, which is the opposite of the intended hardening goal.

CLock all users

Locking user accounts affects user-level authentication but does not prevent the wireless network from being visible during passive RF scanning.

DDisable SSID broadcastingCorrect

When SSID broadcasting is disabled on a wireless access point, the network name is omitted from beacon frames, so the network does not appear in the available networks list on client devices. Users who already know the exact SSID can still connect manually by entering the network name directly. This satisfies the requirement of keeping the network hidden from casual discovery while remaining accessible to authorized users.
