Solution

The correct option is B Violet
Energy of the photon depends on the frequency of the incident light it is directly proportional to the frequency and inversely proportional to the wavelength. As in visible light spectrum frequency increases in the order
$r e d < y e l l o w < o r a n g e < g r e e n < b l u e < i n d i g o < v i o l e t$ . Violet light has greater frequency than green light hence it will have greater energy.
