(D) Flagellated male gametes (antherozoids) are typically found in groups that require water for fertilization,such as Bryophytes,Pteridophytes,and some Gymnosperms.$1$. $Riccia$ is a Bryophyte,which produces flagellated antherozoids.$2$. $Dryopteris$ is a Pteridophyte,which also produces flagellated antherozoids.$3$. $Cycas$ is a Gymnosperm,which is unique among seed plants for having flagellated,motile male gametes.Therefore,the set $Riccia, Dryopteris, Cycas$ contains organisms that all possess flagellated male gametes.
