Decision confidence, correction patterns, intervention results, and explanation satisfaction show where human review improves trust. Final task completion alone is too coarse. Option B is the correct engineering choice because the requirement is not just “make the model answer,” but control the execution surface. The selected option specifically B states “Implement multi-stage evaluation tracking decision confidence scores, user correction patterns, intervention effectiveness, and explainability-satisfaction correlations”, which matches the operational requirement rather than a superficial wording match. That matters because review gates, confidence indicators, provenance views, intervention controls, feedback capture, and auditable decision records. In NVIDIA terms, human oversight becomes measurable when corrections, overrides, confidence, and explanation satisfaction are logged as workflow events. The distractors fail because hiding rationale forces users either to blindly trust the agent or to redo the analysis manually. The result is a system that can be benchmarked, traced, and revised without destabilizing the whole agent fabric. Human review must be designed into the workflow rather than added as an after-the-fact manual workaround.
