Solution

The correct options are
A Gold
B Silver
Some metals like gold (Au), silver (Ag) and copper (Cu) are available in nature in their free state (native) as they are least reactive. Other metals like sodium, potassium, calcium etc., are mostly found in nature in the combined form due to their high reactivity.
