C Correct answer
Explanation

Carbon nanobuds are a newly discovered allotrope of carbon in which fullerene like buds are covalently attached to the outer sidewalls of the carbon nanotubes. This hybrid material has useful properties of both fullerenes and carbon nanotubes. For instance, they have been found to be exceptionally good field emitters.
