In which situation may the fairness of an ICT system be questioned?

Correct answer: The system repeatedly rejects some groups because of incomplete old data

The governing concept is fairness in technology-assisted decision-making. If an ICT system relies on incomplete or outdated data and repeatedly rejects members of particular groups, its results may be unequal and discriminatory. Equal rules, an appeal or review process, and explaining reasons can support accountability, although they still require monitoring. Therefore, option C presents the fairness concern.
