“Horns” are characteristic of a “Bull.” Choose the pair that preserves the specific animal → characteristic appendage relation.

Introduction / Context:
This analogy connects an animal with its characteristic natural appendage. Bulls commonly have horns; we must pick a pair showing a similarly specific and definitive appendage matched to the right animal.

Given Data / Assumptions:

• Bull → horns is a classic animal-to-appendage mapping.
• We seek a unique, taxonomically apt pairing, not just any body part.

Concept / Approach:
“Antlers : Stag” is the closest structural match: antlers are the distinctive deciduous bony structures of male deer (stags). While other options feature real attributes, they vary in generality or category (e.g., “hoofs” are not unique to horses). The bull’s horns parallel the stag’s antlers as iconic head appendages of specific animals.

Step-by-Step Solution:
1) Identify that the relation is “animal → signature head appendage.”2) Compare options for uniqueness and specificity.3) Choose “Antlers : Stag.”

Verification / Alternative check:
In zoological context, antlers are strongly associated with stags; the mapping is as canonical as bull → horns.

Why Other Options Are Wrong:

• Mane : Lion: True attribute, but mane is not an appendage and exists only in males; still, “antlers : stag” better mirrors “horns : bull.”
• Wattles : Turkey: Soft tissue adornment; less parallel to horns.
• Hoofs : Horse: Hooves are common to many ungulates; not as distinctive.

Common Pitfalls:
Confusing uniqueness with general attributes; seek the closest analog to horns.

Final Answer:
Antlers : Stag
