The correct answer is c. Lycophytes have tracheids. Ferns are pterophyta that have developed a vascular system, as with Ginkgos (which are gymnosperms) and flowers (angiosperms). Lycophytes don’t have euphylls however (they have microphyll, which is a leaf with a single vascular strand/vein), which are true leaves present in ferns+allies, gymnosperms, and angiosperms. All of the choices, however, possess multicellular embryo, gametangia, cuticle (waxy covering to prevent water loss) and stomatal (except for liverworts).
