Which guidelines or principles ensure accessibility on mobile devices?

• A. W3C Guidelines
• B. Fluid image
• C. Responsive design
• D. Mind map

Answer: (A)

Focusing on accessibility across devices is anchored by guidelines from the W3C. These guidelines, known as WCAG, set formal, testable criteria that apply to mobile as well as desktop, covering how content is perceivable, operable, understandable, and robust. They guide everything from readable text and sufficient color contrast to touch-friendly controls, predictable navigation, and compatibility with assistive technologies. Because WCAG provides a standardized benchmark used worldwide, it’s the most appropriate reference for ensuring mobile accessibility. A fluid image is a technique for resizing images with the viewport; it helps layouts adapt but doesn’t establish accessibility criteria. Responsive design is a broad approach to make layouts work on various screen sizes, which supports usability on mobile but isn’t itself a set of accessibility guidelines. A mind map is unrelated to accessibility standards.
