Answer 1

daimond I think it is

Answer 2

c) fullerene.

Larger scale structures of the carbon include nanotubes, nanobuds as well as nanoribbons.

Many unusual forms of the carbon exist at high temperatures and extreme pressures.

500 hypothetical 3-periodic allotropes of the carbon are called at the present time according to SACADA database.
