Wireframes primarily focus on displaying the basic layout and functionality of a design. They serve as skeletal frameworks that outline the structure and placement of elements within a digital interface, such as a website or application. Wireframes are typically devoid of color, graphics, or detailed styling, allowing designers to focus on the layout and functionality before moving on to visual design elements. So, the correct answer is: "Displaying basic layout and functionality."
