Trusted Tester 9C emphasizes which principle for UI elements that serve the same function?

• A. Inconsistent labeling of elements with similar functions.
• B. Labeling that changes across sections to reflect design variety.
• C. Consistent identification and labeling of components that perform the same function throughout a website.
• D. Avoid labeling of duplicate components.

Answer: (C)

Consistency in how UI elements that perform the same function are identified and labeled across a website is essential. When every button or control with the same purpose uses the same label and behavior, users quickly recognize patterns, learn expectations, and move through tasks more efficiently. This also supports accessibility, as assistive technologies rely on predictable labeling to navigate by function. If labeling varies by section or changes across pages, users must re-learn each time, increasing errors and frustration. Therefore, the best approach is to maintain consistent identification and labeling of components that perform the same function throughout the site; inconsistent labeling or omitting labels for duplicates undermine usability and accessibility.
