Solution
The correct option is C C and D
A hermaphrodite is an organism having both male and female sex organs and can produce gametes associated with both the sexes. For example, many tunicates, slugs and earthworms and tapeworms are hermaphrodites. They are incapable of self-fertilization and hence, reproduce via cross-fertilization only. Hence, statements A and B are incorrect and statements C and D are correct
So, the correct answer is 'C and D'.
