Which cloud service model provides developers with a platform to develop, run, and manage applications without worrying about the underlying infrastructure?

Platform as a Service (PaaS) provides a platform that allows developers to build, test, and deploy applications without managing the underlying infrastructure like servers, storage, and networking. PaaS abstracts the infrastructure layer and offers development tools, middleware, and database management to streamline the development process, focusing on building and running applications. Option A (IaaS) is incorrect because Infrastructure as a Service (IaaS) provides basic computing resources such as virtual machines and storage but requires the user to manage the platform and applications. Option B (SaaS) is incorrect because Software as a Service (SaaS) delivers complete software applications, not platforms for development. Option D (DaaS) is incorrect because Data as a Service (DaaS) focuses on delivering data on demand, not application platforms. Option E (FaaS) is incorrect because Function as a Service (FaaS) provides a serverless execution model where functions are triggered by events, but it is not a comprehensive development platform like PaaS.
