(B) The relationship between the action spectrum and the absorption spectrum of photosynthesis was first demonstrated by $T.W. Englemann$. He used the green alga $Cladophora$ and placed it in a suspension of aerobic bacteria. He observed that the bacteria accumulated mainly in the regions of blue and red light of the split spectrum. This experiment showed that the rate of photosynthesis is highest in the blue and red regions of the visible spectrum,which corresponds to the absorption peaks of chlorophyll $a$ and $b$.

In photosynthesis,the action and absorption spectrum were related by:
