Answer:
Correct Answer: C
Solution:
The cloacal aperture is an elongated opening at the root of the tail between two anal fins.
It leads into the cloaca into which the intestine and urinary and genital ducts open.
There is a pair of openings situated as the elevated papillae on either side of the cloaca, these are the abdominal pores.
Through these pores, the coelom communicates with the exterior.
