The term 'solid conductor' refers to:

• A. A conductor with numerous small strands bonded together
• B. A single, continuous strand of metal
• C. A conductor with embedded insulation
• D. A fiber optic conductor

Answer: (B)

A solid conductor is a single, continuous piece of metal that conducts electricity. It isn’t made from many small wires bound together. The option describing one continuous strand matches this definition. The other options describe a stranded conductor (many individual wires), a conductor with embedded insulation (insulation around the conductor, not about its solid vs stranded form), and a fiber optic conductor (which carries light, not electricity).
