Question

All of the following are monoecious, except:

• A. Fasciola
• B. Spongilla
• C. Ascaris
• D. Ctenoplana

Answer 1

The correct option is C Ascaris

• Monoecious animals are those animals, which contain both male and female reproductive organs together. They are also called hermaphrodites i.e.; both eggs and sperm are produced by the same individual. E.g. Spongilla, Fasciola, Ctenoplana.
• Dioecious animals are those whose sexes are separate i.e.; egg and sperm are produced by female and male individuals respectively. E.g. Ascaris.

So, the correct answer is option C.
