Attached is the experiment details. I found the exercise on the internet.
The pigments of the algae, according to the experiment, absorb the most strongly around the violet-blue and red parts of the spectrum and so photosynthesis is the most efficient when the algae are under such wave lengths. The results were that more oxygen-seeking bacteria gathered around the algae that were under such wave length because there were more production of oxygen.
If the pigments were now to absorb most strongly around the 500 nm to 560 nm, the bacteria would gather the most around the algae under such wavelegth (green light).

Answer:
A. They are all equally related to one another.
Explanation:
In scientific terms, the evolutionary history and relationships of organisms is called phylogeny. Phylogeny describes the relationship of one organism to others, such as which organisms it is thought to have evolved from, which species it is most closely related to, and so forth.
Phylogenetic relationships provide information on shared ancestry but not necessarily on how organisms are similar or different. Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms.
