Write 'True' or 'False' for the following statement:

Nanotubes are formed by fullerenes allotrope of carbon.

The correct option is A True

Fullerene is a crystalline solid form(allotrope) of carbon.

• They are formed by a number of carbon atoms from 60 to 900 forming a cage like structure in the form of a sphere (called as Buckyball) or cylinder (called as Nanotubes).
• Carbon nanotubes (CNTs) are cylindrical molecules made up of single-layer carbon atoms coiled up into sheets called graphene.

Therefore, the given statement is true.
