A. Glass snake
B. Sea snake
C. Rattlesnake
D. Blind snake

Answer 1

Hint: The carnivorous reptiles which belong to the order serpents that are long elongated and legless are called snakes. Snakes are amniote vertebrates that are covered in overlapping scales. Snakes are ectothermic, which means they rely on the heat from the external environment for conducting metabolic activities.

Complete answer: Snakes are cold-blooded carnivorous reptiles. The body of the snake is covered with overlapping scales. Unlike lizards, the species of the snake consists of a skull that has several joints. Due to the presence of a skull in snakes, it makes it possible to swallow the prey which is much larger than their size. The jaws of the snake are highly mobile and have high flexibility. The paired organs such as the kidney in snakes are placed side by side due to their narrow body. Most of the snakes have only one functional lung. Ophisaurus which is commonly called a glass snake is a genus of snake-like lizards. Although they are called glass snakes, they resemble lizards that do not have legs. The body of the glass snake is shiny grey or brownish in color. Sea snakes are also called coral reef snakes. They belong to the subfamily of venomous elapid snakes. They live most of their lives in marine environments. rattlesnakes are true snakes that derive their name due to the presence of a rattle at the end of the tail. Blind snake or Brahminy blind snake is a non-venomous snake. Therefore, out of the four-options glass snake is not a true snake.
So, option A is the correct answer.

Note: Snakes are limbless reptiles that are evolved from the lizard. Many of the lizards look similar to the snake as they lost their limbs independently. The lizards which look like snakes are slowworms and grass snakes. These are not true snakes.
