1, 2 and 3

Justification: The fullerenes are a large class of allotropes of carbon and are made of balls, ‘cages’ or tubes of carbon atoms.
Statement 1: Nanotubes are cylindrical fullerenes.
Their unique molecular structure results in extraordinary macroscopic properties, including high tensile strength, high electrical conductivity, high ductility, high heat conductivity, and relative chemical inactivity.
Nanotubes can be used to reinforce graphite in tennis rackets because they are very strong.
Due to the above mentioned properties, they are also used as semiconductors in electrical circuits.
Statement 3: The nanotube's structure allows it to be used as a container for transporting a drug in the body.
A molecule of the drug can be placed inside the nanotube cage.
This keeps the drug 'wrapped up' until it reaches the site where it is needed.
In this way, a dose that might be damaging to other parts of the body can be delivered safely to, for example, a tumour.
