The correct option is B Cross-fertilization Earthworms are hermaphrodites but they cannot fertilize their own eggs because of their relative position of male and female genital aperture and they are protrandous (i.e. male sex mature earlier than female gametes). So, cross-fertilization takes place instead of self-fertilization.
So, the correct option is 'Cross-fertilization'.
