Solution

The correct option is D Absorption of light energy
Chlorophyll is the photosynthetic pigment that absorbs the light in the red and blue spectrum of the visible spectrum. After absorbing the light, they lose their electron and initiate the light reaction of the photosynthesis.
Hence, the correct answer is 'Absorption of light energy'
