• B. Hermaphrodite but protogynous
• C. Unisexual
• D. Hermaphordite with self fertilization

Answer 1

Answer: (C)

Unisexual

Unlike other trematodes the schistosomes are dioecious i.e, the sexes are separate which means they are unisexual. The two sexes display a strong degree of sexual dimorphism. The male is considerably larger than the female. The male surrounds the female and encloses her within his gynacophoric canal for the entire adult lives of the worms. So, the correct answer is 'Unisexual'.
