C: The main word that gives it away is billing only based on function execution. It is the consumption(dynamic) plan of function apps that gives you that behavior.

When you're using the Consumption plan, instances of the Azure Functions host are dynamically added and removed based on the number of incoming events. This serverless plan scales automatically, and you're charged for compute resources only when your functions are running. On a Consumption plan, a function execution times out after a configurable period of time. https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale Incorrect Answers: the Windows operating system and the App Service plan hosting plan - App Service Plan hosting will have fixed charges based on chosen pricing tier. the Docker container and an App Service plan that uses the B1 pricing tier - App Service Plan hosting will have fixed charges based on chosen pricing tier. the Docker container and an App Service plan that uses the S1 pricing tier - App Service Plan hosting will have fixed charges based on chosen pricing tier. C is the answer
