Including risk scores in the report will help prioritize the organization's response efforts because the risk score quantifies the potential impact and likelihood of the vulnerability being exploited. It allows the organization to focus on the most critical vulnerabilities first. The other options, while important, are not directly related to prioritization: the number of times an antivirus has triggered does not quantify the impact or exploitability of a vulnerability, the list of outdated software only provides information on what needs to be updated without a direct indication of risk, and the aggregated event logs from IDS/IPS systems, while they provide valuable security insights, do not directly relate to the risk posed by specific vulnerabilities.
