Analogy — Match the part-to-whole (attribute/body covering) relation: Scale : Fish

Introduction / Context:“Scale : Fish” expresses a part-to-whole relation where the part is a natural body covering of the whole. We need an option where the first term is similarly a natural covering or integral part of the second organism.

Given Data / Assumptions:

• Scales are integral to fish anatomy.
• Seek an anatomical part→organism mapping, in the same direction (part first, whole second).

Concept / Approach:Reject pairs that are apparel, reversed direction, or class–member relationships. Prefer anatomical coverings linked to the living being they belong to.

Step-by-Step Solution:(a) Lady : Dress → clothing worn, not an anatomical part.(b) Tree : Leaves → reversed direction (whole→part), while the stem is part→whole.(c) Bird : Feather → whole→part direction again reversed.(d) Skin : Man → skin is a natural anatomical covering; matches part→whole direction and type.

Verification / Alternative check:“Scale→fish” parallels “skin→man” as coverings intrinsic to the organism.

Why Other Options Are Wrong:(a) Apparel, not anatomy; (b) and (c) invert the direction.

Common Pitfalls:Overlooking order of terms (part first vs whole first) in analogy problems.

Final Answer:Skin : Man
