Explanation

Disabling SSID broadcast is considered security through obscurity and provides minimal protection because SSIDs are still transmitted in plaintext within certain 802.11 wireless frames, such as probe request and probe response packets exchanged when a client connects, and in management frames. A passive attacker using a wireless sniffer (e.g., Wireshark, Kismet) can capture these frames and easily discover the hidden SSID. SSIDs are still used for authentication (A is false), are not in all broadcast packets by default when hidden (C is false), and are fully supported in 802.11 protocols (D is false).
