The blades of Threat Prevention typically include IPS (Intrusion Prevention System), AntiVirus, AntiBot, Threat Emulation, and Threat Extraction. These components work together to provide comprehensive protection against a wide range of security threats. QoS (Quality of Service) is not part of Threat Prevention; therefore, options A and B are incorrect. Option D is also incorrect as it includes only three of the correct components. Thus, the correct answer is the option listing IPS, AntiVirus, AntiBot, Threat Emulation, and Threat Extraction.
