Which of the following is a factor to enhance the usability of websites?

• A. Readability
• B. Color scheme
• C. Server location
• D. Security

Answer: (A)

Readability is the factor that most directly improves how usable a website is. When text is easy to read and understand, users can quickly scan, comprehend, and locate information without effort. This means clear font choices, appropriate font size, comfortable line height, adequate spacing, and high contrast between text and background—conditions that reduce eye strain and cognitive load. All of these make content approachable and navigable, which is the heart of usability. Color schemes matter and can support readability, but they aren’t the primary lever for usability on their own; poor contrast or flashy colors can hinder readability even if the site looks nice. Server location affects how fast a page loads, which influences usability indirectly, since slow sites frustrate users. Security is essential for trust and safety, but it doesn’t directly make the interface easier to use.
