Solution
The correct option is A Pollen tube
In ferns there are no pollen tubes to carry sperms, therefore the pollen tubes are not a part of the fertilization process. In ferns, on the underside of the prothallus the sex organs form the female structure, called as an archegonium, which contains a single egg. The male structure, the antheridium, contains many flagellated sperm. The sperm are released from the antheridium and swim through a thin film of water to a nearby archegonium to fertilize the egg. Since the antheridium and archegonium are on the same prothallus the fern has several ways to prevent self-fertilization. Once fertilization of the egg has occurred, a diploid zygote has been created.
