Which one of the following statements correctly differentiates resistance and resistivity of a conductor?
(a) Both resistance and resistivity have the same SI unit Ω.},{
(b) Resistance depends on the conductor’s length and area, whereas resistivity is independent of its dimensions.
(c) Resistance is independent of the conductor’s dimensions, whereas resistivity varies with both length and area.
(d) Resistivity decreases when the cross-sectional area of a conductor is increased, whereas resistance remains unchanged.
