Forward Bias Characteristics of a Junction Diode

Which of the following statement is not correct when a junction diode is in forward bias :
The width of depletion region decrease
Free electrons on n-side will move towards the junction
Holes on p-side move towards the junction
Electrons on n-side and holes on p-side will move away from junction

Solution:

In forward bias, the applied field opposes the barrier field, pushing major carriers (electrons on n-side and holes on p-side) towards the junction, thereby decreasing the depletion width. Thus, statement (4) is incorrect.
