Which of the following is a factor that improves layout usability?

• A. Layout
• B. CDN Deployment
• C. Load Balancing
• D. API Keys

Answer: (A)

Layout usability hinges on how information is arranged on the screen so users can quickly scan, locate, and interact with elements. A good layout uses a clean grid, consistent alignment, ample whitespace, and a clear visual hierarchy, which makes content easy to read and actions easy to perform. That direct control over organization and presentation is what makes the layout the best factor for usability. In contrast, deploying a content delivery network improves load times by caching assets, load balancing spreads requests to keep the site fast and reliable, and API keys govern access and security. These support usability in broader ways but do not directly shape how the content is laid out for the user.
