Correct option is B
Power loss: The power loss in an inductor is related to its resistance and frequency, which are key factors in selecting an inductor.
Quality factor: The quality factor Q of an inductor is defined as the ratio of the inductive reactance to the resistance. It indicates the performance of the inductor, and thus, it is important in its selection.
Current rating: The current rating of the inductor determines how much current it can handle without overheating, which is a critical parameter in selecting the correct inductor.
Dielectric constant: This property is related to capacitors, not inductors. The dielectric constant affects the capacitance of a capacitor and does not directly influence the selection of an inductor.
