When $\text{p}-\text{n}$ junction diode is forward biased, then

• A

  the depletion region is reduced and barrier height is increased
• B

  the depletion region is widened and barrier height is reduced
• Correct answer
  C

  both the depletion region and barrier height are reduced
• D

  both the depletion region and barrier height are increased

Hence, the correct answer is option: 'C'.
