Answer 1

Answer: (E)

All of the above

Earthworm is a hermaphrodite i.e. ovaries and testes are present in the same individual. There are two pairs of testes present in the 10^th and 11^thsegments. Testes are enclosed by a fluid-filled sac called testes sac. Testis sec with the pair of a funnel attached to the vasa deferentia, which run up to the 18^th segment where they join the prostatic duct. In the earthworm reproductive system, four pairs of spermathecae, two pairs of seminal vesicles and one pair of the prostate gland are present.

So, 'All of the above'
