The material composed of C₆₀ molecule that contains sixty carbon atoms in a network of sp² bonding which forms a spherical structure, is known as

Explanation-

Let us observe some definitions and facts of different carbon allotropes

Buckminsterfullerene-

• These are carbon allotropes that are arranged in shape particle .
• They contain 60 carbon atoms arranged in pentagons and hexagon geometry similar to soccer ball.
• In this structure all carbons are equivalent and each atom has sp² bonding.

Haeckelite- 

• These are 3 fold coordinated networks of carbon atoms which are generated by periodic arrangements of different polygons.
• These structures are only proposed theory and yet to be synthesised in laboratory  

Carbon Nanocone- 

• These are conical shaped structures that are predominantly made from carbon.they have the height and the base diameter of the equal magnitude.
• The cone apex angle of the nanocones are not arbitrary but preferred angles are approximately in the range 20°,40°and 60°.

Carbon Nanotube -

• These are cylindrical tubes like structure made up of carbon.
• The structure of an ideal single walled carbon nanotube is that like a regular hexagonal lattice structure drawn on a cylindrical surface,where the vertices indicates the position of carbon atoms.

let us observe the shape of buckminsterfullerene

containing 60 carbon atoms with sp² bonding.

• also known as Bucky Balls
• it is most common naturally occurring fullerene
• it is insoluble in water

Therefore from given options only buckminsterfullerene satisfies the required statement.

Hence the correct option is 1
