Hint: A collection of vascular plants (xylem and phloem plants) that reproduce through spores and have no seeds and no flowers. They sexually reproduce and that requires meiosis and fertilisation.
Complete answer:
> Option A is incorrect. Algae are a diverse bunch of aquatic organisms which can perform photosynthesis. There are three typical reproductive methods found in algae are (i) vegetative (Binary fission in Diatoms, fragmentation in Spirogyra), etc, (ii) asexual (Zoospores in Ulothrix, Alpanospores in Microspora, etc), and (iii) sexual (Autogamy in diatoms, Hologamy in Chlamydomonas, Oogamy in Chara). Besides these processes, some perennial bodies often grow which are faced with adverse conditions.
> Option B is correct. Sporocarp is a reproductive system for some aquatic ferns, such as Marsilea. Sporocarps are leaves that are functionally and developmentally modified and carry many sori. Each consists of two types of sporangia -mega sporangia which produces simple large female megaspore and microsporangia which produces several small male microspores.
> Option C is incorrect. The pistil is the female reproductive structure found in flowers in angiosperms, and consists of the stigma, form, and ovary. An angiosperm has two parts: a male part, and a female part. The female gametophyte is composed of eight cells within an ovule. The stamen is a flower's male reproductive structure; typically consisting of thin, thread-like filaments surmounted by anthers that hold the pollen.
> Option D is incorrect. Bryophytes produce enclosed reproductive structures (gametangia and sporangia) but no flowers or seeds are produced. and replicate by spores. Bryophytes are commonly known to be a group of paraphyletic and not a group of monophyletic, although some studies have reported contrary results.
Hence, The correct answer is option (B).
Note: Ferns reproduces plants (sporophytes) and gamete forming plants (gametophytes) by spores and by alternating generations of different spores. They need water to swim. That means ferns can only replicate successfully in wet areas, or after a storm. The sporophyte grows on top of the gametophyte after fertilisation.
