Tree is to bark as human is to what?

• A. skin
• B. bone
• C. heart
• D. hair

Answer: (A)

The relationship between "tree" and "bark" is that bark is the external protective covering of a tree, much like how skin serves as the protective barrier for a human body. Both bark and skin provide important protection for their respective organisms.

In the context of the human body, skin functions as a critical component that shields the internal organs and maintains overall health, just as bark protects the tree from pests, diseases, and environmental conditions. This analogy emphasizes the protective function that both elements serve, establishing a strong parallel between the two pairs.

The other options do not share this same external protective relationship. Bone is an internal structure, heart is an internal organ essential for circulation, and hair, while it contributes to the overall appearance and has protective qualities, does not serve as the main protective barrier for the body in the same way that skin does. Thus, skin is the most logical and consistent answer in establishing this analogy.
