Which option transfers the relation structure gold -> Au; silver -> Ag with element -> symbol to iron?

Answer options

• Option: Ag
  "Ag" vs. "Fe" Ag is a same-class symbol, but remains; misses the target mapping. Ag carries relation readback element -> symbol. The task targets this mapping, so Ag remains wrong in this prompt.
• Option: Cu
  "Cu" vs. "Fe" Cu is a plausible same-class element; misses the target mapping. Cu carries relation readback element -> symbol. The task targets this mapping, so Cu remains wrong in this prompt.
• Correct: Fe
  "Fe" - target Fe is the element symbol for iron and correctly transfers the. Fe carries relation readback element -> symbol. The task targets this mapping, and Fe remains correct in this prompt.
• Option: Au
  "Au" vs. "Fe" Au is an element symbol from the same; misses the target mapping. Au carries relation readback element -> symbol. The task targets this mapping, so Au remains wrong in this prompt.

Solution

Fe

Fe is correct: gold -> Au; silver -> Ag documents relation element -> symbol; for iron, Fe is the unique target. The prompt targets Fe, so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

relationship_transfer requires multiple source relations, a target anchor, and exactly one structurally equivalent target value. Fe carries the additional dataset detail element -> symbol. The graph therefore uses a multi-hop graph path;
