Solution
The correct option is C Bipinnaria
Redia is a larval stage of certain trematode parasites, which develops in the body of a snail host and gives rise to daughter rediae.
Cercariae are 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.
Miracidium is the free-swimming ciliated larva in which parasitic fluke passes from the egg to its first host.
All these are larval stages of flatworms.
Bipinnaria larvae are the first stage in the larval development of most starfish,
Thus, the correct answer is option C.
