Correct Answer
D
Explanation
has a property that allows current to flow in only one direction. This property is known as the diode's "unidirectional conductivity." When an alternating current passes through a diode, it allows current to flow in one direction while blocking it in the opposite direction, effectively converting the alternating current into direct current. This makes diodes essential components in rectifier circuits used to convert AC to DC in various electronic devices and power supplies.
