Correct Answer: Earthworm

Solution : The correct answer is Earthworm.

Earthworms have both male and female reproductive organs, making them hermaphrodites. They cannot, however, self-fertilize. They instead share sperm with each other during copulation.Cross-fertilization is required for offspring to be produced. This is due to the fact that hermaphrodite sperm and eggs are incompatible. If a hermaphrodite self-fertilized, the offspring would be genetically identical to the parent, which would be harmful to the species.
