What WLAN client device behavior is exploited by an attacker during a hijacking attack?

A.
When the RF signal between a client and an access point is disrupted for more than a few seconds, the client device will attempt to associate to an access point
with better signal quality.

B.
When the RF signal between a client and an access point is lost, the client will not seek to reassociate with another access point until the 120 second hold down
timer has expired.

C.
After the initial association and 4-way handshake, client stations and access points do not need to perform another 4-way handshake, even if connectivity is lost.

D.
As specified by the Wi-Fi Alliance, clients using Open System authentication must allow direct client-to-client connections, even in an infrastructure BSS.

E.
Client drivers scan for and connect to access points in the 2.4 GHz band before scanning the 5 GHz band.
