Answer

Carbon nanotubes conduct electricity due to the presence of delocalised electrons. These delocalised electrons are free to move throughout the nanotube structure, allowing them to carry charge. When an electric field is applied, these electrons flow along the nanotube, facilitating electrical conduction.
