Solution
Temperature
Explanation:
Resistivity is an intrinsic property of a material that depends only on the nature of the substance and its temperature. It does not change with physical dimensions like length, thickness, or cross-sectional area. For metals like copper, rising temperatures increase atomic vibrations, causing more electron collisions and higher resistivity.
