Correct Answer:
A. Egg
This analogy tests your knowledge of the primary products derived from specific animals. The first pair, "Cow : Milk," establishes a clear animal-to-product relationship, where milk is the primary consumable product that a cow provides to humans. Following this pattern, we need to identify the primary consumable product that a hen provides.
- A: Egg is the correct answer. Just as cows are known for producing milk, hens are primarily known and raised for producing eggs, which are a staple food source globally. This maintains the consistent relationship of an animal providing a specific consumable product.
- B: Feather is incorrect because while a hen has feathers, they are a part of its body covering, not its primary consumable product.
- C: Nest is incorrect because a nest is a structure built by a hen (or other birds) to lay eggs in, not a product derived from the hen itself.
- D: Bird is incorrect because "bird" is a general category that includes hens, but it is not a product that a hen produces.
Thus, the complete analogy is Cow : Milk :: Hen : Egg, consistently linking the animal to its most recognized consumable output.
