Comprehensive and Detailed Explanation From Exact Extract:

Google’s SRE approach emphasizes a blameless postmortem culture as a core learning mechanism. After a major outage, SRE teams conduct structured analyses to understand the root causes, contributing factors, and systemic weaknesses. The SRE Book defines this culture explicitly: “Postmortems are written analyses following incidents, designed to capture what happened, why it happened, and how to prevent the issue from recurring.” (SRE Book – Chapter: Postmortem Culture). This learning-focused approach reduces blame, increases resilience, and improves future reliability.

Option C aligns exactly with this principle.

Option A (follow-up culture) is vague and not an SRE term.

Option B (major incident culture) refers to incident handling, not learning afterward.

Option D (problem culture) is unrelated to SRE’s structured post-incident learning.

Thus, C is correct.
