Solution

The correct option is D Chlorophyll owes its colour to non- absorption of green light
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. The green light is not absorbed but reflected, making the plant appear green
So, the correct answer is 'Chlorophyll owes it’s color to non- absorption of green light’
