These fields belong to the Attacks Risk Report. Cisco defines Total Attacks as the number of IPS events and Hosts Targeted as the number of unique destination addresses associated with relevant IPS events. Events Requiring Attention represents the proportion of intrusion events with an impact flag indicating relevance.
Hosts Connected to CnC Servers identifies unique hosts associated with the "CnC Connected" indication-of- compromise category. Together, these measurements summarize attack activity, affected assets, and potentially compromised systems. A Network Risk Report focuses on broader network-level risk and does not use this exact field collection. "Events Risk Report" and "Hosts Risk Report" are not the applicable standard risk-report templates. List B incorrectly marks Network Risk Report; Cisco's report documentation explicitly assigns all four fields to the Attacks Risk Report, so the verified answer is B. Cisco risk-report templates

Change Reconciliation records snapshots whenever users save system-configuration changes and combines those snapshots into a detailed report covering the previous 24 hours. Under System > Configuration > Change Reconciliation, the administrator enables the feature, selects the daily execution time, and specifies management's recipient email addresses. The administrator can also include policy-configuration changes and enable the full change history instead of receiving only a consolidated view. An email relay host must be configured so that Management Center can deliver the report. Sending audit logs to an HTTP or syslog server streams audit events to an external collector; it does not generate the required daily email summary. STIG Compliance applies security-hardening settings and is unrelated to scheduled change reporting. Cisco Change Reconciliation documentation
