Solution

The correct option is D Metacercariae
  • Platyhelminthes contain worms that cause parasitic and non-parasitic infections in humans and other mammals. Liver fluke is an endoparasite.
  • The fluke completes its life cycle with the help of two hosts. The primary host is sheep and its secondary or intermediary host is the freshwater snail.
  • Liver fluke infects the snail at the miracidium stage and sheep at the metacercaria stage. Hence, option A is correct.
