AForensic analysisCorrect
BRisk assessment

A risk assessment identifies potential risks and their likelihood/impact *before* an incident occurs, but after an incident, RCA is needed to understand the specific failure that materialized.

CRoot cause analysis
DBusiness impact analysis (BlA)

A Business Impact Analysis (BIA) quantifies the financial and operational impacts of an outage, helping prioritize recovery efforts, but it doesn't explain *why* the outage occurred or how to prevent it, which is crucial for determining mitigating controls.
