Azure Functions is the correct answer as it embodies the principles of serverless computing. In serverless architectures, the cloud provider manages the infrastructure, allowing developers to focus solely on writing code without worrying about server management, provisioning, or scaling.

With Azure Functions, code execution is event-driven, meaning that functions are triggered by specific events such as HTTP requests, timers, or messages from a queue. This ensures that users only pay for the compute resources their code uses during execution, rather than for a pre-allocated server. The platform automatically scales based on demand, which is a hallmark of serverless technology, making it highly efficient for applications with variable workloads.

In contrast, other options like Azure Virtual Machines and Azure Kubernetes Service involve the management of underlying server infrastructure. Both require users to provision and manage virtual servers or clusters, which goes against the serverless model. Azure App Service also provides a managed platform for web applications, but it offers a different model where the underlying environment is abstracted away to a degree, yet it still requires some resource management and tends to involve more traditional hosting approaches than what is seen in serverless computing.
