Assertion : Earthworm show cross fertilisation. Reason : Earthworm is hermaphrodite
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Earthworm are hermaphrodite which means both male and female reproductive organs are present in the same individual. Selffertilization will not occur because the testes mature earlier than the ovaries, Such a condition is called Protandry. Self fertilization will not occur also because of the relative position of opening of male and female reproductive organs(gonopores).

Which of the following structures in Pheretima is correctly matched with its functions?
1 Setae - defence against predators
2 Typhlosole - storage of extra nutrients
3 Clitellum -secretes cocoon
4 Gizzard-absorbs digested food
