Solution

The correct option is D Has all the above properties
Absorption spectrum of a substance is an electromagnetic spectrum in which a decrease in intensity of radiation at specific wavelengths or ranges of wavelengths is a characteristic of the light absorbing substance.
Absorption spectra of chlorophyll shows all of the mentioned properties.
Absorption spectrum of chlorophyll explain the green colour of chlorophyll.
It is approximate to action sepectrum of photosynthesis and the rate is different at different colour or wavelength of light.
