A.none of these.
B.type of material.
C.length of the conductor.
D.area of the conductor.
Explanation: The resistivity is a property of material, defined as the resistance between two opposite faces of a cube of a material of unit volume. That is why resistivity is only the unique property of material and it does not depend upon the dimension of any piece of material.
