Solution
The correct option is C Cercaria
Cercaria: a free-swimming larval stage in which a parasitic fluke passes from an intermediate host (typically a snail) to another intermediate host or to the final vertebrate host.
Sporocyst: a parasitic fluke in the initial stage of infection in a snail host, developed from a miracidium.
Redia. : a larva produced within the sporocyst of many trematodes that produces another generation of larvae like itself or develops into a cercaria.
metacercaria. : a tailless encysted late larva of a digenetic trematode that is usually the form which is infective for the definitive host.
