A technology vendor markets an AI system capable of predicting employees' 'flight risk' using behavioral data including keystrokes, email metadata, and application usage. Which risk is MOST significant for an employer considering deploying this system?

Here's the deal — b is correct because covert keystroke and behavioral monitoring raises severe privacy concerns (potentially violating wiretap laws, GDPR, and state privacy regulations), and using predicted flight risk in employment decisions (e.g., targeting employees for reduced opportunities) could constitute discrimination if the prediction correlates with protected characteristics. A, C, and D are operational concerns secondary to the fundamental legal and ethical risks.
