Hi @Snow preck 

The correct answer is:

B. As many as the application design requires

In ServiceNow, the number of application menus an application can have is not limited. You can create as many application menus as needed based on the requirements and design of your application. Each menu can group a set of modules that logically belong together, making navigation easier for users with different roles and responsibilities. This flexibility allows you to tailor the user experience to best fit the needs of your organization and the application’s functionality.
