Which of the following is a component used in user interfaces?

Buttons are fundamental components in user interfaces because they serve as interactive elements that users can engage with to execute specific actions. In digital design, buttons provide a straightforward way for users to navigate, submit forms, or trigger other functionalities, making them essential for creating an effective user experience. They are typically coupled with visual indicators such as color, shape, and text that guide users on what action will occur when they click or tap them.

In contrast, while analytics tools may provide insights into user behavior, they do not directly interact with users in the interface. Marketing frameworks focus on strategies and methodologies for promoting products, which are important for business success but not components of the user interface itself. Business goals outline the objectives of a project or organization and influence design decisions but do not constitute interactive elements within the user interface. Thus, buttons clearly stand out as a core component in the context of user interfaces.
