Two other major groups of flavonoids found in flowers
and leaves of all green plants. The function of these two flavonoids in plants
are____
a) protect plants against being eaten by herbivores
and against being infected by microbial pathogens
b)
Protect cells from excessive UV-B radiation (280–320 nm) because they
accumulate in the epidermal layers of leaves and stems and absorb light
strongly in the UV-B region
c)
flavones and flavonols secreted into the soil by legume roots mediate the
interaction of legumes and nitrogen-fixing symbionts
d) They are are coloured terpenoid compounds that also
serve as accessory pigments in photosynthesis

The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.
Based on the tabular data, and assuming that time advances vertically, which phylogenetic tree is the most likely depiction of the evolutionary relationships among these five species?
