The correct answer is option 'C' - Two pairs of testes in 10th and 11th segments.
Explanation:
Earthworms, specifically Pheretima, are hermaphroditic organisms, which means they have both male and female reproductive organs. These reproductive organs are located in specific segments of the earthworm's body.
Here's a detailed explanation of the location of the body parts mentioned in the options:
a) Four pairs of spermathecae in 4 - 7 segments:
Spermathecae are the female reproductive organs that store and receive sperm from the male during mating. In Pheretima, there are not four pairs of spermathecae in segments 4-7. Spermathecae are actually present in segments 5 and 6 in Pheretima.
b) One pair of ovaries attached at the intersegmental septum of 14th and 15th segments:
Ovaries are the female reproductive organs that produce eggs. In Pheretima, the ovaries are not attached at the intersegmental septum of the 14th and 15th segments. Instead, they are located in the 13th and 14th segments.
c) Two pairs of testes in 10th and 11th segments:
Testes are the male reproductive organs that produce sperm. In Pheretima, there are indeed two pairs of testes located in the 10th and 11th segments.
d) Two pairs of accessory glands in 16 - 18 segments:
Accessory glands are present in the male reproductive system and produce fluids that aid in the movement of sperm. In Pheretima, the accessory glands are not located in segments 16-18. Instead, they are located in segments 17 and 19.
Therefore, the correct answer is option 'C' - Two pairs of testes in 10th and 11th segments.
