Choose the false option -

Options

A. Most reptiles are terrestrial
B. Reptiles have 3 or 3.5 chambered heart except crocodile (has 4 chambered heart)
C. Snakes and lizards shed their skins as skin cast
D. Reptiles are viviparous

Answer

To determine the false option from the given statements about reptiles, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Analyze the first statement**: "Most reptiles are terrestrial."
- This statement is true. Most reptiles, such as lizards and snakes, primarily live on land.

2. **Analyze the second statement**: "Reptiles have 3 and 3.5 chambered heart except crocodile."
- This statement is also true. Most reptiles have a heart with three chambers (two atria and one ventricle), while crocodiles are an exception as they have a four-chambered heart.

3. **Analyze the third statement**: "Snake and lizard shed their skin as skin cast."
- This statement is true as well. Snakes and lizards do shed their skin, and this process is known as ecdysis, where they shed the outer layer of skin.

4. **Analyze the fourth statement**: "Reptiles are baby parrots."
- This statement is false. Reptiles are not baby parrots; they are a distinct class of animals that includes snakes, lizards, turtles, and crocodiles, among others. Parrots are birds, which belong to a different class altogether.

### Conclusion:
The false option is: "Reptiles are baby parrots."
