Deauthentication frames are part of the 802.11 protocol and are used to terminate an existing wireless association between a station and an access point. However, they can also be spoofed by an attacker to disrupt or hijack wireless connections. The other options are not effective or relevant for this purpose. Performing jamming on all 2.4GHz and 5GHz channels would interfere with all wireless signals in the area, which may cause unwanted attention or legal issues. Setting the malicious AP to broadcast within dynamic frequency selection channels would not help, as these channels are used to avoid interference with radar systems and are not commonly used by wireless stations or access points. Modifying the malicious AP configuration to not use a pre-shared key would not help, as it would make it less likely for wireless stations to connect to it if they are configured to use encryption.
