The correct answer is B. Platform as a service. Here's why:
* Context of the Question: The organization wants to run a custom application in the cloud in a flexible and scalable way without managing any infrastructure.
* Google Cloud Product Relevance:
* Platform as a Service (PaaS) provides a platform that allows customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the underlying infrastructure.
* Google Cloud's App Engine is an example of a PaaS offering. It enables organizations to deploy custom applications in a fully managed environment where scaling, load balancing, and infrastructure management are handled automatically.
* Why Not Other Options:
* A. Infrastructure as a service: IaaS requires the organization to manage the underlying infrastructure (like virtual machines, networks, and storage), which is not suitable if the organization does not want to manage any infrastructure.
* C. Network as a service: NaaS is focused on network connectivity and does not provide the capabilities needed to run custom applications.
* D. Software as a service: SaaS provides pre-built applications managed by a provider; it is not suitable for running custom applications.
