 Resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. The S.I. unit of electrical resistance is the ohm (Ω).
 
The resistance (R) of an object is defined as the ratio of voltage across it (V) to current through it (I).
That is, R= V/I  ( Derived by ohm’s law)
So the answer is C) ohm
