The following are found in Taenia solum, which one is the correct sequence?

Oncosphere or hexacanth is the larval stage of the Taenia solium (tapeworm) which migrates from the intestine to internal tissues or organs within the intermediate host. An oncosphere develops into a cysticercus which is a bladder metacestode from that parasitizes tissues of the intermediate host, mainly pigs, and humans. The cysticercus further develops into a mature tapeworm called matured proglottid. Mature proglottids are released from the tapeworm's end segment and leave the host in feces or migrate as independent motile proglottids. The gravid proglottids release eggs which are shed and the further life cycle continues. These eggs are discharged from gravid proglottids in the small intestine are passed in the feces. So, the correct sequence is A.
