Final answer:
Hermaphroditism is when an individual has both male and female reproductive parts. They can self-fertilize or mate with another individual of their species. Hence, c) is correct.
Step-by-step explanation:
Hermaphroditism occurs in animals where one individual has both male and female reproductive parts. Invertebrates such as earthworms, slugs, tapeworms, and snails are often hermaphroditic.
Hermaphrodites may self-fertilize or may mate with another of their species, fertilizing each other and both producing offspring.
Self fertilization is common in animals that have limited mobility or are not motile, such as barnacles and clams.
