Solution

The correct option is B $0.6$
The impedance of the circuit is given as,

$Z = \sqrt{R^{2} + X^{2}}$

$= \sqrt{{(3)}^{2} + {(4)}^{2}}$

$= 5 o h m$

The power factor of the circuit is given as,

$cos ϕ = \frac{R}{Z}$

$= \frac{3}{5}$

$= 0.6$

Thus, the power factor of the circuit is $0.6$ .
