(B) The power factor of an $AC$ circuit is given by the formula $\cos \phi = \frac{R}{Z}$,where $R$ is the resistance and $Z$ is the impedance of the circuit.For an ideal choke coil,the resistance $R = 0$.Since the coil is purely inductive,the impedance $Z = X_L = \omega L$.Substituting these values into the formula,we get $\cos \phi = \frac{0}{Z} = 0$.Therefore,the power factor of an ideal choke coil is $0$.
