Vedclass · Answer

(D) In forward biasing,the positive terminal of the battery is connected to the $p$-side and the negative terminal to the $n$-side of the $p-n$ junction diode.This external electric field opposes the internal electric field of the junction.As a result,the width of the depletion region $(x)$ decreases and the potential barrier height $(V_B)$ also decreases.Therefore,the correct option is $D$.
