The correct answer is Find opportunities to strengthen incident response procedures.

A lessons learned review exists to identify what worked and what did not work during the incident and to convert those findings into concrete improvements to playbooks tools communications and training so the organization can respond more effectively to future incidents.

Collect forensic evidence for investigation is important but it is a tactical activity performed during incident handling and evidence preservation. It is not the primary goal of the post incident review which focuses on systemic improvements.

Pinpoint staff failures for accountability is incorrect because a lessons learned review should avoid blame and instead focus on process gaps and opportunities for training and support.

Determine the attacker's identity can be part of forensic and attribution work but it is not the main objective of an internal lessons learned review which is concerned with the organization response and how to strengthen it.
