I believe the correct answer among the choices listed above is the last option. Plants seemed to evolve in the order of bryophytes, gymnosperms,angiosperms. Bryophytes are mosses that lack vascular tissue. Gymnisoerm do not have seeds but have vascular tissue. Angiosperms have flowers and seeds for mating.
