Durable Functions is the correct option.

Durable Functions adds an orchestration programming model to Azure Functions so one function can call and coordinate other functions while preserving state across long running workflows and across restarts. It provides orchestrator functions and activity functions and it manages durable timers and reliable state so you can implement fan out and fan in patterns or human interaction workflows.

Extension Bundles is not correct because extension bundles only provide a mechanism to simplify installing function extensions and they do not themselves implement stateful orchestration.

Azure Functions Core Tools is not correct because that toolchain helps you run and deploy functions locally and it does not add an orchestration or state management extension.

Azure Logic Apps is not correct because Logic Apps is a separate managed workflow service and not an Azure Functions extension that you install to provide durable orchestration within functions.
