A medical diagnostics company is deploying an agentic AI system to assist radiologists in analyzing...

At production scale, Option A preserves separability between reasoning, state, tools, and runtime operations. Radiology is safety-critical, so AI should present evidence, confidence, and recommendations while radiologists approve and document rationale. Autonomous final diagnosis is not acceptable. Operationally, the design depends on interfaces that show recommendations, evidence, risk drivers, and immediate accept/modify/reject actions. The selected option specifically A states “Design an interactive system that presents AI analysis with confidence scores, allows radiologists to review evidence, modify recommendations, and requires explicit approval with documented reasoning for all decisions.”, which matches the operational requirement rather than a superficial wording match. The alternatives would look simpler in a prototype, but high-level summaries without drill-down prevent experts from verifying whether the recommendation is grounded. For a production build, NVIDIA-style production governance pairs guardrails and observability with user-facing controls so interventions are traceable. It also creates clean evidence for audits, incident review, and root-cause analysis when behavior drifts. Human review must be designed into the workflow rather than added as an after-the-fact manual workaround.
