Final answer:
Rekha should use a Box (C) in her wireframe to represent the content and banner for a website's home page. This visual placeholder indicates the size and placement of elements and helps focus on the layout during the initial design stages.
Step-by-step explanation:
If Rekha is creating a wireframe and wants to represent the content and a banner for the home page effectively, she should use C) Box. A Box in wireframing represents a container for various UI elements, and it can symbolize anything from graphics and video players to text and images. In this instance, the Box would serve as a visual placeholder for the actual banner and content areas on the website's home page, depicting their size, placement, and how they relate to other elements on the page.
Wireframes are crucial in the design process as they lay out the structural foundation of a page before visual design and content are added. They do not typically involve any color, font choices, logos, or real images. Using the Box allows Rekha and her team to focus on the website's layout without getting distracted by details that are typically addressed later in the design process.
