Solution

The correct option is A Flagellated antherozoids
Bryophytes are the amphibians of the plant Kingdom. Even though survive on land, they need water to complete their life cycle. Antherozoids are flagellated and are motile and swim towards the female gamate to carry out fertilisation. This motile male gamete and its dependence on water point towards an aquatic origin.
