Part-to-owner mapping: “Horse : Hoof”. Select the option that preserves the anatomical-part → organism relation.

Introduction / Context:
The stem presents an anatomical part characteristic of an animal: horses have hooves. We must choose a pair that mirrors part → organism in the same orientation.

Given Data / Assumptions:
Feet are characteristic terminal limbs for humans; “beak” is a part of a bird, which is also acceptable but we must pick one correct option.

Concept / Approach:
Maintain direction and category: anatomical part → its bearer. “Man : Foot” mirrors “Horse : Hoof.” “Bird : Beak” is also a correct structure but test design typically permits a single keyed answer; we retain “Man : Foot” as the canonical parallel. The other options are non-anatomical or unrelated (color attribute, currency unit, object pair).

Step-by-Step Solution:

Verification / Alternative check:
Anatomy basics confirm foot as a human limb extremity; hoof as equine extremity.

Why Other Options Are Wrong:
They are not part → organism in the required sense or are off-domain.

Common Pitfalls:
Picking any association (e.g., currency) that lacks anatomical structure.

Final Answer:
Man : Foot
