The correct option is To establish formal thresholds for acceptable residual risk.

Risk acceptance criteria set measurable thresholds that tell an organization when remaining risk after controls is acceptable. These criteria link risk decisions to the organizations risk appetite and business objectives and they provide a consistent basis for accepting, treating, or escalating risks.

To attempt to identify every possible threat or vulnerability is incorrect because that describes a scope of risk identification rather than criteria for accepting residual risk. Acceptance criteria do not require exhaustive discovery of every threat.

Cloud Security Command Center is incorrect because it is a product name rather than a definition of risk acceptance criteria. It does not describe thresholds or limits for acceptable residual risk.

To mandate complete removal of all risks is incorrect because eliminating all risk is usually impossible and often impractical. Risk acceptance exists precisely because some residual risk must be tolerated or managed in other ways when full elimination is not feasible.
