Explanation

Faithfulness (B) and Relevance (D) are the standard RAG-specific evaluation metrics because they directly measure what RAG is designed to do: retrieve pertinent information and generate responses grounded in that retrieved context. Faithfulness checks whether the generated answer is factually consistent with the retrieved documents (no hallucinations), while Relevance measures whether the retrieved chunks and final answer actually address the user's query.

Carbon footprint (A) is a general sustainability metric unrelated to RAG quality - it says nothing about whether the system retrieves or generates accurately. Speed (C) is a performance/latency metric that applies to any software system; it doesn't capture the accuracy or quality of retrieval and generation that define RAG effectiveness.

Memory tip: Think "FAR" - Faithfulness and Relevance are the two pillars of RAG quality. Faithfulness = "did the model stay true to what it retrieved?" and Relevance = "did it retrieve and return what the user actually needed?"
