02) The resistivity of the conductor depends on

 area of the conductor.

 length of the conductor.

 type of material.

 none of these.

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.
