The unrooted phylogeny in the figure shows the relationships among proteobacteria. Which of the following would be true if the root were placed on the branch between nodes A and B? a. C. violaceum is more closely related to P. diminuta than it is to E. coli. b. Z. ramigera is more closely related to E. coli than it is to C. violaceum. c. P. diminuta is more closely related to Z. ramigera than it is to E. coli. d. E coli is more closely related to P diminuta than it is to Z. ramigera.
