The plant kingdom is divided into the five phyla which can be distinguished on the basis of the defining features shown by the plants.

The spores are produced by these sporophytic structures of higher plants that do not form in the large size gametophyte but reduced gametophyte or microscopic gametophyte, therefore, is least useful to the classification.

Thus, E) spores is the correct answer.
