Consider habitats: Lion and cow are primarily land-dwelling animals. Choose the analogous set for water habitat.

Introduction / Context:Habitat analogies require pairing organisms with their characteristic environment. The stem highlights land habitat via two animals (lion, cow). The correct choice should mirror that structure for a water habitat, i.e., two water-associated animals with the habitat named alongside them.

Given Data / Assumptions:

• Lion, cow → land habitat.
• We seek a parallel example illustrating water habitat.

Concept / Approach:Whales are fully aquatic; hippopotamuses are semi-aquatic and closely tied to rivers/lakes. Pairing these animals with “water” mirrors the land example and preserves the analogy “animals → habitat”. Options that present unrelated lists or geopolitics fail the ecological framing required here.

Step-by-Step Solution:

Verification / Alternative check:Chairs and tables are furniture, not organisms; countries are places, not habitats of animals in the biological sense. An amphibious example (frog, crocodile) with “riverbank” could be close but is not provided as a neat parallel like whales + hippos with “water”.

Why Other Options Are Wrong:They either ignore biology, mix categories, or lack a clear habitat mapping.

Common Pitfalls:Choosing sets that do not explicitly express the “animal ↔ habitat” relation.

Final Answer:Whale : Hippopotamus : Water
