To review assessment findings and formally accept or reject the system risk for operation is correct.

The Approving Official is the individual who holds the authority to grant or deny the system permission to operate. They review the assessment findings and the risk assessment report and then formally accept residual risk if the level is tolerable or reject the system until required mitigations are implemented.

Cloud Security Command Center is incorrect because it refers to a product or tool rather than the role that makes the authorization decision during the Authorize step.

To create and implement technical security controls is incorrect because implementing controls is the responsibility of system owners and engineers during the Implement step and not the Approving Official who makes the risk acceptance decision.

To perform routine operational monitoring of the system is incorrect because continuous monitoring is part of the Monitor step and is carried out by operations and security teams rather than by the Approving Official.
