Solution
The correct option is A Snail
Blood fluke is the Schistosome which is a parasitic trematode. Thousands of eggs are released and reach the bladder or the intestine and these are then excreted in urine or feces to freshwater. The larvae must pass through an intermediate snail host, which is its secondary host, before the next larval stage of the parasite emerges that can infect a new mammalian host by directly penetrating the skin.
So, the correct answer is option A.
