Why each option

Antivirus software is the best choice because it acts as a preventive logical control by blocking malware and a corrective logical control by removing existing infections.

ASecurity awareness training

Security awareness training is a preventive administrative control that educates users, but it does not technically correct or remediate a security incident on a system.

BAntivirusCorrect

Antivirus software serves as a preventive logical control by employing real-time protection and signature-based scanning to stop malware from initially infecting a system. Concurrently, it functions as a corrective logical control by detecting, quarantining, and removing malicious software that has already breached defenses, thereby remediating the system post-infection.

CFirewalls

Firewalls are primarily preventive logical controls that block unauthorized network traffic, but they do not actively clean or remove malware from an infected system.

DIntrusion detection system

An Intrusion Detection System (IDS) is a detective logical control that identifies and alerts on suspicious activity, but it does not actively prevent intrusions or correct system infections itself.
