This scenario is an example of overreliance . Microsoft’s AI guidance highlights that Copilot is an assistive tool that can accelerate analysis and drafting, but users remain responsible for validating outputs—especially for high-impact business decisions. Overreliance occurs when someone treats AI output as authoritative and acts on it without applying judgment, cross-checking sources, or validating against current conditions.

Here, the merchandiser uses Copilot to generate stocking recommendations from historical sales data, then places a large order without reviewing the suggestions or incorporating current market trends. Even if the historical data is accurate, demand can shift due to seasonality changes, competitor actions, pricing, supply constraints, macroeconomic factors, or new product launches. Copilot’s recommendations should be treated as a starting point for decision-making, not the final decision.

Option A (verification) is the opposite behavior—checking accuracy before acting. Option C (fabrication) would involve Copilot inventing facts; the prompt doesn’t indicate fictional data, only unvalidated reliance. Option D (prompt injection) involves malicious instructions embedded in content to manipulate the model, which is not described here.

Therefore, the best answer is overreliance .
