Final Answer:
The statement given "PaaS that hosts web apps provides full control of OS." is false because PaaS (Platform as a Service) abstracts the underlying infrastructure, and users do not have full control of the operating system. Option B is the answer.
Step-by-step explanation:
Platform as a Service (PaaS) is a cloud computing service that provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of underlying infrastructure. In the case of PaaS that hosts web apps, it does not offer full control of the operating system (OS) to the users. PaaS abstracts the infrastructure layer, including the operating system, to simplify application deployment and management.
Unlike Infrastructure as a Service (IaaS), where users have more control over the OS, PaaS abstracts such details to streamline the development process. PaaS providers manage the underlying infrastructure, allowing developers to focus on coding and deploying their applications without concerning themselves with OS-level details.
Option B is the answer.
