The correct answer is: A. PaaS

PaaS (Platform as a Service) is a cloud computing model that provides a platform for developing, testing, and deploying applications. The platform includes a set of tools and services that abstract away the underlying infrastructure, such as servers, storage, and networking. This allows developers to focus on building their applications without having to worry about managing the underlying infrastructure.

PaaS is a good option for businesses that need to develop and deploy applications quickly and easily. It is also a good option for businesses that do not have the resources to manage their own infrastructure.

Here is a brief explanation of each option:

  • B. IoT service provider is a company that provides services to connect and manage devices and applications in the Internet of Things (IoT). IoT service providers typically offer a platform that allows businesses to connect their devices, collect data, and analyze it.
  • C. SaaS (Software as a Service) is a cloud computing model that provides software applications over the Internet. SaaS applications are typically accessed through a web browser and are hosted by the software provider.
  • D. IaaS (Infrastructure as a Service) is a cloud computing model that provides access to computing resources, such as servers, storage, and networking, over the Internet. IaaS providers typically offer a pay-as-you-go pricing model, which allows businesses to only pay for the resources they use.
