A conductor consists of a single wire or a combination of uninsulated strands, as this structure allows for effective electrical conduction. Conductors are materials that permit the flow of electric current due to their low resistance. The uninsulated strands can be made of metals like copper or aluminum, which are often used due to their excellent conductivity. This design also enhances flexibility and performance, especially in applications where flexibility and durability are required, such as in cables and wiring.

Insulation plays a crucial role in defining the safety and functionality of a conductor by preventing accidental contact with conductive materials or components. While a conductor may include insulated wires, the essence lies in the materials that facilitate the flow of electricity, which are usually in the form of strands or wires rather than solid components.

The option that mentions a solid piece of metal outlines a type of conductor but lacks the flexibility and acknowledges that combinations of strands are often more efficient in practical applications. A circuit board is not considered a conductor in this context, as it typically incorporates various components and materials, including conductors, resistors, and capacitors, all working together to manage electrical pathways.
