Hint: The pair of fins that are said to be located on the underside of the fish's body is known as the Pelvic fins. In general, these Pelvic fins are said to be attached to the pelvic girdle. These pelvic fins take the responsibility of controlling the direction. The fishes can rest on sitting on the pelvic fins. The pelvic fins' function, which is present on the shark's stomach, is to balance the shark in the water. A male anatomical structure organ which is used in mating is called a clasper. Typically, it is formed from the posterior portion of the pelvic fin.
Complete answer:
Pelvic fins in males of Chondrichthyes are ones that bear claspers.
In males of Chondrichthyes like rays and sharks, pelvic fins bear specialized claspers.
At the time of copulation, one clasper is put into the female's cloaca. During this, the sperm is pushed by the male's body via a groove into the female's body.
When the clasper is inserted into the cloaca, it opens like an umbrella to hold its position.
Clasper is a paired male insect organ that is used to clasp females during copulation.
It assists the movement of spermatozoa into the female body during copulation.
Hence, the correct answer is option D.
Additional Information:
Chondrichthyes class contains cartilaginous fishes. People say that these are examples of jawed vertebrates with paired fins, paired nares, scales, their skeletons are said to be made up of cartilage rather than bone, and they have a heart where its chambers are in series. Claspers are present only in males. Claspers are crucial for reproduction.
Note:
As mentioned earlier, the clasper is the so-called paired male insect organ used to clasp females during copulation. It is said that the clasper is formed from the posterior portion of the pelvic fin. The pelvic fins form the claspers in males of Chondrichthyes. At the time of copulation, claspers are used to transfer sperms into the female's cloaca and assist spermatozoa's movement into the female body during copulation. Claspers are present only in males. Claspers are crucial for reproduction.
