Answer: Option (A) is the correct answer.
Explanation:
It is known that metals are malleable and ductile. Whereas non-metals are neither malleable nor ductile.
On the other hand, metalloids are the elements which contain properties similar to both metals and non-metals.
Therefore, if a material is ductile, it is most likely a metalloid because it is not necessary that ductility is a property shown by metals only.
Wherease like non-metals, noble gases are also neither malleable nor ductile.
