Concept:Forward bias reduces the junction barrier and narrows the depletion layer, enabling current flow.
Explanation:In forward bias, the positive terminal of the battery is connected to the p-side and the negative terminal to the n-side.
This applied voltage opposes the built-in potential barrier of the junction.
As a result, the barrier voltage decreases, not increases.
With a lower barrier, the depletion layer width decreases.
This allows majority charge carriers (holes from p-side and electrons from n-side) to cross the junction easily.
Therefore, electric conduction becomes possible, not impossible.
Hence, the correct statement is that the width of the depletion layer decreases.
Answer:Option B: width of depletion layer decreases.
