A developer wants to run code in response to events without managing infrastructure. Which Azure service is best?

Azure Functions is a serverless compute service that allows you to run event-driven code without provisioning or managing infrastructure. This aligns perfectly with the developer's need to respond to events without infrastructure management. Azure Virtual Machines require you to manage the operating system and all software, which is contrary to the requirement. Azure Kubernetes Service (AKS) is a container orchestration platform that still involves managing clusters and nodes, albeit at a higher abstraction level than VMs. Azure SQL Database is a relational database service, not a compute service for running code.
