Integrated autoscaling with preconfigured development stacks to accelerate application delivery is correct because it describes the core PaaS value proposition of reducing operational burden and speeding deployments.

PaaS solutions provide managed runtimes and platform services so developers can focus on code and features rather than operating system updates or runtime configuration. They often include built in autoscaling and preconfigured development stacks which accelerate application delivery by removing the need to provision and maintain the underlying platform.

Google Kubernetes Engine is incorrect because it is a managed Kubernetes service that focuses on container orchestration and cluster control. That requires more infrastructure and operational management than a typical PaaS and is closer to a container platform than a pure PaaS.

Simplified transfer of data across multiple cloud vendors without extra migration tooling is incorrect because PaaS does not inherently solve cross cloud data migration. Portability and data transfer often require specific design and tooling and are not the primary benefit of choosing a PaaS.

Complete administrative control of the underlying physical hardware and network configuration is incorrect because PaaS removes that level of low level control from the customer. The provider manages the hardware and networking so teams trade that control for reduced operational overhead and faster delivery.
