Question

Using the graph on nucleotides answer the phylogeny question.

I'm confused about which tree would match better. The top phylogenetic tree seems correct, but it doesn't match the graph. I feel the bottom phylogenetic tree matches the graph. I'm not sure can anyone explain which would be correct?
