The correct option is A Schistosomiasis
Schistosomiasis is an acute and chronic disease caused by blood flukes. People become infected when larval forms of the parasite released by freshwater snails and penetrate the skin during contact with infested water. Transmission occurs when people suffering from schistosomiasis contaminate freshwater sources with their excreta containing parasite eggs, which hatch in water. In the body, the larvae develop into adult schistosomes. Adult worms live in the blood vessels where the females release eggs. Some of the eggs are passed out of the body in the feces or urine to continue the parasite’s life cycle. Others become trapped in body tissues, causing immune reactions and progressive damage to organs. So, option B is correct.
