Correct answer: (d) 1 only
Explanation
Noble metals are highly unreactive, so they occur in nature in their pure (native) form – Statement 1 is correct.
True noble metals are gold, silver, platinum and the platinum group; uranium and lead are not noble metals – Statement 2 is wrong.
They have high melting points and strong corrosion resistance.
