After a security incident is verified in a SOC, an incident responder reviews the incident but cannot identify the source of the incident and form an effective mitigation procedure. To whom should the incident ticket be escalated?

a SME for further investigation
a cyberoperations analyst for help
an alert analyst for further analysis
the SOC manager to ask for other personnel to be assigned

Option A i.e., SME for further investigation.

The ticket for an incident must be applied to SME for even more inquiry. So, the following answer is correct.
