In ServiceNow, the Application Picker is a user interface element that allows developers to select the active application they are working on. The selected application determines the Application Scope, which defines the boundaries within which application artifacts (like tables, scripts, and UI components) reside and operate.

A. Selecting Global in the Application Picker sets the Application Scope to Incident: This is incorrect. Selecting " Global " sets the scope to the global application, not specifically to the Incident application.

B. Global is a reserved application that does not appear in the Application Picker: This is incorrect. The " Global " application is available in the Application Picker and represents the global scope.

C. Selecting an application from the Application Picker sets the Application Scope: This is correct. Choosing an application from the Application Picker establishes that application ' s scope as the current context for development and configuration.

D. Selecting an application from the Application Picker does not set the Application Scope: This is incorrect. The Application Picker directly influences the current Application Scope.

For more information, refer to the official ServiceNow documentation on Application Scope.
