Question

Crocodile : Whale : Hippopotamus

• A. They are animals
• B. They are domestic animals
• C. They are land animals
• D. They are water animals

Hint:

These animals are aquatic or semi-aquatic—crocodile (freshwater), whale (marine), hippopotamus (freshwater).

Answer 1

The Correct Option is D

In this question, we are asked to determine the common categorization for Crocodile, Whale, and Hippopotamus. The options provided suggest different ways to categorize these animals. Let's analyze each option:

1. They are animals: While it is true that Crocodile, Whale, and Hippopotamus are animals, this is a very broad category and does not help in identifying a specific shared feature among these three.
2. They are domestic animals: Domestic animals are those that are kept by humans for companionship, work, or food. Crocodiles, whales, and hippopotamuses are not typically domestic animals.
3. They are land animals: Land animals are those that primarily live on land. Among the three, only the Hippopotamus can be considered a land animal, even though it spends a significant amount of time in water.
4. They are water animals: Water animals are those that primarily live in water. Crocodiles live in freshwater habitats, whales live in the ocean, and hippopotamuses inhabit rivers and lakes. Thus, all three spend significant time in water, making this the most fitting category.

Therefore, the correct answer is:

They are water animals.
