D Correct answer
Explanation

Gold is a noble metal that doesn't readily oxidize or react with other elements, allowing it to exist in pure metallic form (native state) in nature. Unlike silver, copper, or bronze (which is an alloy), gold is found in nuggets or veins in its elemental form without chemical processing. This property has made gold valuable throughout human history.
