Option 3 is correct, i.e. Moss. Bryophytes are small, non-vascular plants, such as mosses, liverworts, and hornworts.

Cycas belongs to the family of Cycadaceae.
Pteridophytes are primitive vascular plants, commonly known as ferns.
The life cycle of ferns is split between free-living gametophytes and sporophytes phases.
Ferns are the member of a bunch of vascular plants (plants with vascular tissue and phloem) that reproduce via spores and have neither seeds nor flowers.
The ferns constitute an ancient division of vascular plants and as old as the Carboniferous Period.
