RUB stands for which concept?

The idea being tested is how bending a conductor affects its electrical resistance. When a wire or fiber is forced to bend, the actual path the current travels becomes slightly longer and the cross-section around the bend can experience strain, which can increase the effective resistance and the associated losses. This increase is captured by the concept of Resistance Under Bend, making it the best match for what RUB stands for. The other options describe the radius, a riser context, or rupture, none of which specifically refer to how resistance changes when a bend occurs.
