Why does a PN-junction diode not conduct current when reverse biased?

• A. Excess holes in P-type material combine with the electrons in N-type material, converting the entire diode into an insulator
• B. Only P-type semiconductor material can conduct current
• C. Holes in P-type material and electrons in the N-type material are separated by the applied voltage, widening the depletion region
• D. Only N-type semiconductor material can conduct current
