Why each option
In a PaaS model, the cloud provider manages most of the underlying infrastructure, leaving the tenant responsible for their applications.
The hypervisor is part of the underlying infrastructure managed by the cloud provider in a PaaS model.
While an application runs on a virtual machine, the VM itself (including the OS and runtime environment) is managed by the cloud provider in PaaS, not the tenant.
The network infrastructure, including its maintenance and patching, is managed by the cloud provider in a PaaS model.
In a Platform as a Service (PaaS) model, the cloud provider manages the operating system, virtualization, servers, storage, and networking. The tenant's primary responsibility is to develop, deploy, manage, and patch their own applications and the data associated with them running on that platform.
