The width of the space charge region at a p-n junction is reduced by applying a voltage bias over the p-n junction. What is the correct statement on both the bias voltage and the p-n junction?

A. The voltage is a forward bias and the diffusion of the majority charge carriers becomes more dominant.
B. The voltage is a reverse bias and the diffusion of the majority charge carriers becomes more dominant.
C. The voltage is a forward bias and the drift of the minority charge carriers becomes more dominant.
D. The voltage is a reverse bias and the drift of the minority charge carriers becomes more dominant.
