Answer:
The correct answer is option d. "The various substituents on the tetrapyrrole ring alter the absorption properties of the pigments".
Explanation:
In chlorophyll and bacteriochlorophyll pigment molecules absorb light energy for photosynthesis at different spectrums. The means at which absorption spectrum is controlled is by the fact that the various substituents on the tetrapyrrole ring alter the absorption properties of the pigments. The tetrapyrrole ring has a a magnesium atom at its center, which in conjuction acts as an antenna for light's absorption.
