The correct answer is Configuration then General Settings.

Open your App Service in the Azure portal and use the Configuration blade. The General Settings area inside Configuration is where you choose the runtime stack and version so you can select Python 3.10 for that app. This setting applies to the individual App Service and causes the platform to provide the chosen Python interpreter for your application.

Settings then Properties is incorrect because the Properties page shows basic resource metadata such as region and subscription and it does not allow you to change the runtime version.

App Service Plan then Apps is incorrect because the App Service Plan controls compute resources and scaling and it is not where you configure an individual app's runtime stack. You may see apps hosted in a plan there but you cannot set the Python version for a specific app from that view.

Deployment then Deployment Center is incorrect because the Deployment Center is used to configure source control and deployment pipelines and it does not set the platform runtime or the Python version for the app.
