Vedclass · Answer

(A) Earthworms are bisexual (hermaphrodite) animals,meaning they possess both male and female reproductive organs.However,they exhibit cross-fertilization because the maturation of sperm and eggs occurs at different times,a condition known as protandry.During mating,two earthworms exchange sperm,which is then stored in the spermathecae to fertilize the eggs later.Therefore,the correct answer is $A$.
