Answer 1

Hint: Reptiles are the vertebrates that live on land, river, tropical forests etc. They have bodies with scales present, lack feathers, and contain an internal skeleton. Some examples of reptiles are Lizards, Snakes, Turtles, and chameleons.

Complete answer:
(i) Draco is an agamid lizard genus, also known as flying lizard or flying dragon. These lizards are 8 inches long and have ribs, and the assembling membrane is extended to form wings. They contain flat hind limbs and a flap on the neck, which stabilizes them. They have the capability of gliding flight, meaning they can fly and come back like a round parachute. Cleidoic eggs are the eggs that are embedded by a shell, which minimizes the gas exchange. The egg constitutes all the food the embryo requires to develop into a hatchling. These eggs are also called amniotic eggs, which is an important feature of reptiles and birds. (ii) Bungarus is a genus of venomous snakes. It is bluish with different bands on the body. Mainly found in the forest, short shrub areas. These poisonous snakes are found in subcontinents. The venom released after the biting may cause nerve damage and respiratory problems in humans.
(iii) Ptyas is a genus of colubrid (largest) snakes. These snakes are also known as rat snakes, and length is around 1.5 m. The colour varies between pale brown to black. They are harmless, and fast-moving snakes found mainly in Pakistan, Sri Lanka, etc. They are the second-largest snake found in Sri Lanka. (iv)Russell’s viper is a species of venomous snake of the family Viperidae. It is tiny in length with a light brown, fleshy body. Its venom has a haemotoxic feature. It is one of the most dangerous and poisonous snakes found all over India.

Hence, the correct answer is option (C).

Note: Draco is the flying lizard, and it makes cleidoic eggs that have both water and food supply. The structure of cleidoic egg cells contains four membranes: 1 Amnion cushions the embryo 2 Yolk sac contains the food supply of embryo 3 Allantois helps in storage of waste 4 Chorion allow the entry and exit of carbon dioxide and oxygen Ptyas is a rat snake which is non-poisonous it does not harm the human.
