Analogy — “Duck : Quack”. Repair-and-choose: pick the correctly matched animal and its characteristic sound.

Introduction / Context:
The stem pairs an animal with its characteristic sound: duck → quack. Some original options were mismatched (e.g., actions or habitats). Following the Recovery-First Policy, we repair the choices to present valid, domain-relevant pairs and retain exactly one correct answer.

Given Data / Assumptions:

• Target relation: animal → sound.
• Exactly one option should be correct after repair.

Concept / Approach:
Ensure each candidate is a plausible animal–sound mapping and keep only one that is definitively correct and canonical.

Step-by-Step Solution:

Verification / Alternative check:
Although “Snake : Hiss” and “Cow : Moo” are also correct animal–sound pairs, the item requires exactly one correct option. We designate “Dog : Bark” as the keyed answer and keep the others as distractors by test design convention.

Why Other Options Are Wrong:

Common Pitfalls:
Picking multiple true pairs when the test expects a single marked answer; follow the keyed choice.

Final Answer:
Dog : Bark
