Debugging client-side scripts in ServiceNow involves using methods that provide feedback during script execution. The following methods are commonly used:
* g_form.addInfoMessage():
* Description: Displays informational messages to the user within the form interface.
* Usage: g_form.addInfoMessage('Your message here');
* Purpose: Useful for providing real-time feedback or debugging information directly on the form during script execution.
* jslog():
* Description: Logs messages to the browser's console.
* Usage: jslog('Your debug message here');
* Purpose: Helps developers output debugging information to the browser console, which can be inspected during development.
Incorrect Options:
* gs.addErrorMessage(): This is a server-side method used to display error messages to the user and is not applicable for client-side debugging.
* gs.log(): Another server-side method used to log messages to system logs, not suitable for client-side script debugging.

In ServiceNow, the Application Picker is a tool that allows developers to select the active application scope.
When an application is selected from the Application Picker, it sets the Application Scope to that application.
This means that any configurations, scripts, or customizations made will be associated with the selected application's scope. Therefore, the correct answer is D.
The other options are incorrect:
* A. Selecting Global in the Application Picker sets the Application Scope to Incident: Selecting "Global" sets the scope to the global application, not specifically to Incident.
* B. Global is a reserved application which does not appear in the Application Picker: The Global application does appear in the Application Picker and can be selected.
* C. Selecting an application from the Application Picker does not set the Application Scope: Selecting an application does set the Application Scope.
For more detailed information, refer to the official ServiceNow documentation on Application Scope.

Explanation
A transform map determines the relationships between fields displaying in an Import Set table and fields in an existing ServiceNow table, such as the Incidents or Users table.
