The correct answer is B.
OBJ-1.7: When conducting a vulnerability scan, it is common for the report to include some findings that are classified as “low” priority or “for informational purposes only.” These are most likely false positives and can be ignored by the analyst when starting their remediation efforts. “An HTTPS entry that indicates the web page is securely encrypted” is not a false positive but a true negative (a non-issue). A scan result showing a different version from the automated asset inventory should be investigated and is likely a true positive. A finding that shows the scanner compliance plug-ins are not up-to-date would likely also be a true positive that should be investigated.
