The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.

In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.

Thus, gymnosperms and angiosperms is the right answer.
