Answer 1

The correct option is B

1,2 and 5 only
Explanation:

A carbon nanotube is a nano-size cylinder of carbon atoms.
Properties of carbon nanotubes:

• High thermal and electrical conductivity
• Optical properties
• Flexibility
• Increased Stiffness
• High tensile strength (100 times stronger than steel per unit of weight)
• Lightweight
• Ability to be manipulated yet remain strong
