The flukes are parasitic in the liver, blood vessels, lungs, bladder, and elsewhere in vertebrate The sheep liver fluke (Fasciola hepatica) is a common parasite of sheep and cattle, which become infected by eating aquatic plants containing encysted metacercariae (juvenile flukes). Humans can acquire the parasite by eating raw watercress (which grows naturally at the edges of lakes and ponds and is cultivated in many countries in Asia and Europe) containing the metacercariae of the fluke.

So, the correct answer is option A. Answer verified by Toppr They are acoelomates and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. Planaria, liver fluke, and Taenia all are flat worms. So, the correct answer is option A. Answer verified by Toppr Whereas flukes are flattened and generally leaf-shaped, adult tapeworms are flattened, elongated, and consist of segments called proglottids. The terminal segments are gravid, with the egg-filled uterus as the most prominent feature.
