Answer 1

Correct Answer - Option 4 : 1, 2, 3 and 4

Carbon Nanotubes (CNT): These are modes of carbon with diameters typically measured in nanometers.

Properties:

1. They having electrical & thermal conductivity

2. CNTS are very elastic

3. They have a very high tensile strength

4. They are highly flexible

5. CNTS have a low thermal expansion coefficient

6. CNTS are good electron field emitters
