Chlorophyll a, is efficient to absorb wavelength of light lying on either end of the visible spectrum and not from regions of visible spectrum that lies away from the ends. Thus, plant under blue light will grow the maximum as it receives the suitable light.
While plant which is under the orange light is at some distance from the red end of the visible spectrum. hence it will grow a little less as compared to the plants receiving blue light.
Plant which is exposed to green light will not grow at all as green light is reflected by the plant due to which it appears green in color to us.
Thus, Option A is correct.
