Fullerenes ("Buckeyballs") Are Spherical Molecules Composed Exclusively of Carbon Atoms

Fullerenes ("buckeyballs") are spherical molecules composed exclusively of carbon atoms. What is their connection with meteoric impacts?

A) Fullerenes are not produced naturally on Earth, so any fullerenes found here must have been carried here from space.
B) Fullerenes are not produced naturally on Earth, but they can be created in the tremendous heat and compression of a large meteoric impact.
C) Fullerenes with gas molecules trapped inside could only have been produced in supernova explosions.
D) Fullerenes with gas molecules trapped inside could only have been produced in the tremendous heat and compression of a large meteoric impact.
