Explanation:

Sister - group relationships in phylogenetic trees are determined by which groups share a most - recent common ancestor. In Tree 1 and Tree 2, groups A and B are sister groups (they share a more recent common ancestor with each other compared to their relationship with C). In Tree 3, the sister - group relationships are different.

Answer:

A. Trees 1 and 2 are equivalent.
