Identification of the Odd One Out
In the given options, we have four animals: Tortoise, Duck, Snake, and Whale. To find the odd one out, we need to analyze their characteristics.
Classification of Animals
- Tortoise: A reptile that lives both on land and in water. It is known for its hard shell and slow movement.
- Duck: A bird that is primarily aquatic. Ducks are known for their ability to swim and their distinctive quacking sound.
- Snake: A legless reptile that is also primarily terrestrial. Snakes are known for their elongated bodies and ability to slither.
- Whale: A mammal that lives exclusively in water. Whales are large, intelligent creatures and are known for their complex social structures.
Key Differences
- Habitat:
- Tortoise: Can inhabit both land and water.
- Duck: Primarily aquatic but can be found on land.
- Snake: Mostly terrestrial.
- Whale: Exclusively aquatic.
- Classification:
- Tortoise and Snake are reptiles.
- Duck is a bird.
- Whale is a mammal.
Conclusion
When considering the classification and habitat, the Whale stands out as the odd one. Unlike the others, which are either reptiles or birds, the whale is the only mammal in the group. Additionally, while the tortoise, duck, and snake can be found in various environments (land or water), the whale is entirely aquatic.
Thus, option 'D' (Whale) is the correct answer as it differs fundamentally from the other three animals in both classification and habitat.
