Question

All of the following larval stages belong to Fasciola hepatica except

• A. Cercaria
• B. Miracidium
• C. Glochidium
• D. Redia

Answer 1

The correct option is C Glochidium

Miracidium is the free-living motile form of Trematoda (F. hepatica) covered with cilia, which settles in the mollusc to become a sporocyst.
A redia is a larval form of F.hepatica with an oral sucker, it will produce either more redia and cercariae.
Cercaria is the larval form of the parasite, developed within the germinal cells of the sporocyst or redia.
Glochidium, on the other hand, is a microscopic larval stage of some freshwater mussels, aquatic bivalve molluscs.
So, the correct answer is option C.
