The natural resource that would most likely be found near volcanic arcs of subduction zones is:
A. metal ores
Subduction zones are associated with high temperature and pressure conditions that facilitate the formation of various metal ores, including copper, gold, and silver. The geological processes in these regions contribute to the concentration of these metals. Contrarily, saline water, fresh water, and hardwood lumber are not directly linked to the unique geological conditions found in subduction zones.
