Answer Details
In a reverse biased junction diode, current flows in by minority carriers. When a junction diode is reverse biased, the P-type region is connected to the negative terminal of the battery and the N-type region is connected to the positive terminal. In this condition, the holes in the P-type region and the electrons in the N-type region are both moving away from the junction, creating a depletion region with very few charge carriers. However, due to the presence of a small number of impurities, there are still some charge carriers present in this region, known as minority carriers. These minority carriers can contribute to the reverse current that flows through the diode when a voltage is applied in the reverse direction. Therefore, the correct option is "minority carriers".
