What is the correct classification of club mosses?

Club mosses belong to the phylum Lycophyta, which is a group of vascular plants that are characterized by their small, scale-like leaves and ability to reproduce via spores rather than seeds. This classification is significant because Lycophyta is one of the oldest groups of vascular plants, dating back to the early Paleozoic era.

In contrast to dicotyledonae and angiosperms, which are flowering plants and produce seeds enclosed within fruit, club mosses reproduce via spores produced in cone-like structures. The other options, including Poa (which is a genus of grasses), do not correctly classify club mosses, as they belong to a different phylum entirely. By identifying club mosses as part of Lycophyta, it highlights their unique evolutionary lineage and reproductive strategies separate from seed-bearing plants.
