Answer 1

Right choice is (a) Absolute permeability Easiest explanation: The total permeability is the product of the absolute and the relative permeability. In air medium, the relative permeability will be unity. Thus the total permeability is equal to the absolute permeability given by 4π x 10^-7 units.
