Category–Member Analogy: POETRY : BALLAD :: ____

Introduction / Context:
A ballad is a type (member) of poetry (category). We must choose a pair with the same “class → member” direction.

Concept / Approach:
“Reptile : Snake” mirrors “category : member”.

Why Other Options Are Wrong:
“Snake : Reptile” reverses the direction; others are not a clean category→member mapping.

Final Answer:
Reptile : Snake
