The correct answer is C.
OBJ-3.3: Frequency jamming is one of the many exploits used to compromise a wireless environment. It works by denying service to authorized users as legitimate traffic is jammed by the overwhelming frequencies of illegitimate traffic. There is no indication that the malicious user is creating a rogue AP (which is a form of spoofing) or performing a MITM attack by having users connect through their laptop or device. Also, there is no mention of certain websites or devices being blocked logically. Therefore there is no blacklisting of IP addresses performed.
