Solution

The correct option is B Fasciola
Polyembryony is the phenomenon of two or more embryos developing from a single fertilized egg. Fasciola shows the phenomenon of polyembryony. Germ cells in the sporocyst and rediae are direct descendants of the zygote. These germ cells multiply mitotically and produce subsequent larval stages within the sporocyst and radiae. This process of reproduction in the sporocyst and radia is called polyembryony. Hence, option B is correct.
