Solution

The correct option is C Raises the potential barrier
Reverse bias applied to a p-n junction diode raises the potential barrier because p-type material connected to the negative terminal and pulls the holes away from the junction. Similarly, n-type material connected to the positive terminal and pulls the electrons. Therefore the depletion region widens and this leads to the rise in the potential barrier.
