What does "stranded wire" refer to?

"Stranded wire" refers to wire that is composed of multiple small strands. This construction allows for greater flexibility and easier handling compared to solid wire, which is made from a single thick strand. Stranded wire is commonly used in applications where movement or bending occurs, such as in extension cords or for connecting devices that need some degree of flexibility. This design helps to improve the conductor's resilience to fatigue and breakage, making it ideal for portable applications where the wire may be frequently moved or manipulated.

While other options describe different characteristics or types of wire, they do not accurately define stranded wire. Therefore, the option describing multiple small strands is the correct definition of stranded wire.
