Answer:

Correct Answer: B

Solution:

[b] Asexual reproduction in brown algae happens by the formation of biflagellate gametes.

They are motile zoospores and non-motile neutral spores.

The zoospores produced in the zoosporangia are pyriforms have chromatophore, biflagellate, contain contractile vacuoles and an eye spot.
