Solution
The correct option is B Dugesia
Dugesia is a thinly flattened worm with definite sides. It has a bilateral symmetry which is in direct correlation with progression towards the anterior end. The anterior end forms an obvious head which is triangular with two laterally projecting head lobes or auricles. On the head are two cup-shaped black eyes. Fasciola, Schistosoma, and Echinococcus do not have eyes. So, option B is correct.
