Answer:
Correct Answer: C
Solution:
The hemipenes are the copulatory organs found in Uromastix and some other reptiles.
These are two eversible hollow sacs lying under the skin behind the cloacal aperture at the base of the tail.
Proximally, the hemipenes communicate with the urodeum of the cloaca.
During copulation, only one hemipenis is inserted into the cloaca of the female.
Erection of the hemipenes is due to the muscular action and filling with blood, then they are everted and become cylindrical and project beyond the cloaca.
