How is the voltage drop across a low resistance related to lead resist

1.	How is the voltage drop across a low resistance related to lead resistance?(a) it contains contact resistance(b) it depends on the magnitude of voltage drop(c) it depends on the type of null detector used(d) It does not contain any contact resistanceI got this question in quiz.The doubt is from Measurement of Low Resistance in section Measurement of Resistance of Electrical Measurements
Answer» Correct answer is (d) It does not contain any contact RESISTANCE Best explanation: The voltage DROP measured ACROSS a LOW resistance does not contain any contact and lead RESISTANCES of the components and is independent of it.
