When a photosensitive material is illuminated by photons of energy 3.1 eV, the stopping potential of the photoelectrons is 1.7 V. When the same photosensitive material is illuminated by photons of energy 2.5 eV, the stopping potential of the photoelectrons is

• A

  1.8 V
• B

  1.4 V
• Correct answer
  C

  1.1 V
• D

  1.3 V

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