Solution

The correct option is C Will not change
Resistivity is an intrinsic property of a material that signifies how efficiently a given material opposes the flow of electric current. It does not depend on the dimensions of a resistor. Resistivity is influenced by temperature - for most materials, the resistivity increases with temperature.
Hence, here in the question resistivity remains the same irrespective of the change in dimensions of the conductor.

The correct option is C.
