The absolute method of resistance is wheatstonebridge method (ANSWER B).
because measured resistance is expressed straightly in ohms.

With the help of Ohm's law method we find unknown resistance using
other than ohm measurement units (current and voltage).

And Rayleigh's method uses dimensionless constants.
