C. Both 2 and 3 are correct

Step-by-step solution

Asexual reproduction is by the production of different types of spores, the most common being the zoospores. They are flagellated and on germination gives rise to new plants. Sexual reproduction takes place through fusion of two gametes. These gametes can be flagellated and similar in size as in Chlamydomonas or non-flagellated and non-motile but similar in size as in Spirogyra. Fusion between one large, nonmotile (static) female gamete and a smaller, motile male gamete is termed oogamous, e.g., Volvox, Fucus.
