Solution
The correct option is B Three
Antheridium is the male sex organ while archegonium is the female sex organ in both bryophytes and pteridophytes. Male gametes are motile in both bryophytes as well as pteridophytes and fused with the non-motile female gametes to form zygote.
Protonema are chain of cells which are developed from spores during the life cycle of mosses (bryophytes).
Ovule is the female reproductive structure in seeded plants like gymnosperm and angiosperm. It is not present in bryophytes and pteridophytes.
Vascular tissues are first observed in pteridophytes.
