Solution

Tree B is the right answer. As in a phylogenetic tree, distance matrix represents dissimilarity between the two. More the distance mire the dissimilarity. And the length of the bars represents the distance.

So, the nearest members must be bakeri and nicorae and the other group is notatum and peckii. And the length of the bars representing these groups represents the dissimilarity.
