Software as a Service (SaaS) - Offers ready-to-use software applications managed by the cloud provider, but may not provide the level of customization or control needed for specific regulatory compliance.

Platform as a Service (PaaS) - Provides a managed environment for developing, testing, and deploying applications with built-in compliance and security features, reducing the need for infrastructure management.

Infrastructure as a Service (IaaS) - Offers virtualized computing resources over the internet, giving more control over the infrastructure but requires the organization to manage more aspects of security and compliance.

None of the above - The organization should consider on-premises solutions for better control over security and compliance.
