Explanation
A dorsal fin is a fin located on the backs of various unrelated marine and freshwater vertebrates, including most fish.
The caudal fin is the tail fin, located at the end of the caudal peduncle and is used for propulsion.
The anal fin is located on the ventral surface behind the anus. This fin is used to stabilize the fish while swimming.
Pelvic fin: either of a pair of fins attached to the pelvic girdle of fishes that help to control the direction of movement during locomotion.

Explanation
Correct Answer; C
Explanation:
Mammals are a group of vertebrates that are warm-blooded.
They receive their name due to the presence of mammary glands.
Their skin is covered with hair and it has oil and sweat glands.
Most of the mammals directly give birth to well-developed live young ones, like humans, dogs, cows, etc. but, mammals like platypus and echidna lay eggs while kangaroos are marsupials that give birth to very poorly developed young ones and carry them in a pouch for some time after birth.

None of these
Explanation
Reptiles, the class
Reptilia
, are an evolutionary grade of animals, comprising today's turtles, crocodilians, snakes, lizards, and tuatara. Most reptiles lay amniotic eggs covered with leathery or calcareous shells. They are terrestrial animals and thus egg-laying happens on land. Whereas Pisces which include fishes depend on water for laying eggs. Amphibians also depend on water for their egg-laying process.
So, the correct answer is option C.

Snakes are devoid of organs of locomotion. They move by contraction and relaxation of muscles. They have different types of movement like
serpentine movement, c
aterpillar or reticular movement, s

Snake

Wall lizard
Explanation
Snakes, crocodiles, and birds don't urinate, urea and other water soluble stuff are pushed out with the faeces.
Urinating is a balance between getting rid of waste and keeping hydrated. Birds and reptiles ‘urinate’ in a way to conserve their water. Unlike mammals, which excrete waste fluid (e.g., urea in water) as urine and solid waste as faeces, birds, snakes and crocodiles mix both liquid waste and solid waste into the semi-solid paste.
Thus, they do not possess a urinary bladder.
So, the correct answer is option B.
