A team is evaluating multiple versions of an AI agent designed for customer support.

The selected option specifically C states “Implementing an evaluation framework that quantifies task efficiency and incorporates human-in-the-loop feedback”, which matches the operational requirement rather than a superficial wording match. Continuous refinement requires quantitative efficiency signals and human feedback. One-time tuning before deployment cannot handle drift in user issues or business rules. In a GPU-backed agent deployment, Option C maps closest to how the NVIDIA stack expects orchestration, inference, and control policies to be separated. This lines up with NVIDIA guidance because NVIDIA evaluation tooling emphasizes whole-agent behavior, including tool selection order, final outcome quality, throughput, latency, and traceability. The practical pattern is closed-loop evaluation where benchmark results, user feedback, and parameter changes are versioned together. That is why the other options are traps: looking only at speed can reward broken behavior, while looking only at accuracy can ignore cost and reliability failures. This is exactly where NVIDIA’s stack is strongest: separating acceleration, orchestration, policy, and observability.
