The key requirements are maintaining a specific set of controls, including data residency and personnel data access controls, specifically to meet a highly regulated industry's compliance program.

Assured Workloads is the specific Google Cloud service designed to help customers meet these stringent regulatory and compliance requirements (e.g., FINRA, FedRAMP, HIPAA, etc.) by enforcing a specific control bundle.

Extracts:

"Assured Workloads helps organizations run their sensitive workloads securely and in a compliant manner... by providing continuous compliance monitoring for specific compliance programs." (Source 4.1)

"When you create an Assured Workloads folder, the platform automatically enforces compliance controls... including: Data residency and location controls... Personnel access controls... Organizational policies..." (Source 4.2)

This service creates a dedicated, compliant environment in a folder, ensuring the necessary configurations and personnel controls are applied automatically and continuously maintained, which is a more complete solution than the posture management in option B (which focuses only on configuration monitoring) or the singular organizational policy in option C.
