Classification — sense and organ mapping: pick the pair that breaks the “action : organ” pattern.

Introduction / Context:
Three pairs map a sensory action to the organ that performs it (action → organ). One pair flips the order to organ → sense, disrupting the shared relation direction.

Given Data / Assumptions:

• See : Eyes → action : organ.
• Hear : Ears → action : organ.
• Smell : Nose → action : organ.
• Tongue : Taste → organ : sense (reversed).

Concept / Approach:
Normalize all pairs to the same direction (action → organ) and detect the inversion.

Step-by-Step Solution:

Verification / Alternative check:
Rewriting D as “Taste : Tongue” would align it with the rest.

Why Other Options Are Wrong:
They preserve the same mapping direction.

Common Pitfalls:
Focusing only on correctness; direction consistency is the actual test.

Final Answer:
Tongue : Taste
