Answer is Wrong!
Answer is Right!
The correct answer is C. C – 60.
C60 is a fullerene, a type of allotrope of carbon with a cage-like structure. It is the most stable fullerene and is also known as buckminsterfullerene or buckyball. The structure of C60 is similar to that of a soccer ball, with 60 carbon atoms arranged in 12 pentagons and 20 hexagons.
The other options are incorrect because they do not correspond to any known allotropes of carbon.
