A city government is building a mobile app AI feature that reads street signs aloud and describes nearby obstacles for pedestrians who are blind or have low vision. During testing, the team specifically recruits users with a range of vision impairments, color blindness, and different reading devices to make sure the feature works well for all of them, not just users who tested it internally. Which responsible AI principle is the team primarily addressing by broadening its test group this way?
Select an answer to reveal the explanation.
Short Explanation
Bringing in testers with different levels of vision loss, color blindness, and different devices is about making sure the feature actually holds up for everyone it is meant to serve, not just the handful of people who happened to be in the room when it was built. That is a different concern from keeping someone's personal data locked down, which is about protecting information rather than testing performance across different users. It is also different from spelling out who is responsible when the system gets something wrong, and different again from explaining how the system arrives at its output in the first place. Here the whole point of widening the test group is to catch gaps that would only show up for someone with a different set of abilities than the original testers, so the feature works about as well for a person with low vision or color blindness as it does for anyone else.
Full Explanation
The correct answer is C. By deliberately recruiting testers with a range of vision impairments, color blindness, and different assistive devices, the team is checking that the feature genuinely works for the full diversity of people who will rely on it, rather than only the narrower group who happened to build or informally test it. That deliberate effort to design and validate an AI system for people with varied abilities and circumstances is the responsible AI principle of inclusiveness. Option A is incorrect because privacy and security concerns how personal data collected by the app is protected from unauthorized access, which is a separate issue from whether the feature performs well across different users' abilities. Option B is incorrect because accountability concerns who remains responsible for the system's outcomes and how oversight is structured, not how broadly the system was tested against user diversity. Option D is incorrect because transparency concerns clearly communicating how the system produces its results so users can understand its behavior, which is different from ensuring the underlying feature itself performs equally well for a wide range of users.
