151727 Statement I : Specific resistance depends on nature of material and independent of temperature of the material.
Statement II : A wire of resistance $6 \Omega$ is drawn out so that its new length is four times its original length. The resistance of the new wire is $48 \Omega$.
Statement III: Drift velocity is the average constant velocity acquired by free electrons inside a metal by the application of an electric field which results in current.
