The correct option is
D Leech
Hermaphrodite animal is a animal which has both male and female reproductive gametes in the same individual. Leech is a hermaphrodite because it has both the reproductive gametes in same individual. The sperms and ova mature at different times so the fertilization is reciprocal which means the leeches use a clitellum to hold their eggs and secrete the cocoon it is fertilized by sperms of another leech.
So, the correct answer is option D.
