Step-by-Step Solution
Step 1: Understand reactivity and occurrence of metals
Gold is a noble metal, least reactive, and commonly found in free (native) state in nature.Step 2: Analyze other metals
Sodium, calcium, and magnesium are highly reactive and not found free in nature.Final Answer:
Gold → Option BQuick Check:
