Which method ensures the visibility of navigation options in a mobile application?

The choice of using menus to ensure the visibility of navigation options in a mobile application is correct because menus provide a structured way to present various navigation links or categories to users, making them easy to access and interact with. Menus can be displayed in different formats, such as hamburger menus, tab bars, or bottom navigation bars, which are common in mobile applications. This format allows users to understand where they are in the application and easily access other areas without cluttering the interface.

Menus also support a wider variety of options compared to other navigational aids, maintaining the app's usability while keeping the design tidy. They can dynamically reveal more options as needed, catering to the limited screen space of mobile devices while also enhancing user experience by providing clear paths to content.

In contrast, sticky navigation bars, while useful for persistent access to certain functions, can take up valuable screen space and may not display all navigation options comprehensively. Popups can be disruptive and tend to interrupt user flow, making navigation less intuitive. Footers can hold navigation options, but they often do not provide a comprehensive view and may not be immediately visible, requiring users to scroll down, which could lead to an overlooked navigation option.
