Answer
material
Reason — Specific resistance (also called resistivity, denoted by ρ) is a material property of a conductor and does not depend on its dimensions. It depends on :
- The type of material (like copper, aluminium, iron, etc.)
- Temperature (resistivity can change with temperature)
But it does not depend on :
- Length
- Area of cross-section
- Radius
