Classification – Odd one out (product vs category) Three pairs show fruit/vegetable → processed product (e.g., jam, squash, puree). One pair shows item → category (hyponym → hypernym). Identify the odd relation.

Introduction / Context:
Many analogy/classification questions contrast “derivative/product” relations with “taxonomic” (category) relations. Correctly naming the relation type is the key to quick, consistent answers across options that otherwise all feel related to food.

Given Data / Assumptions:

• Apple : Jam (apple can be processed into jam)
• Lemon : Citrus (lemon is a member of the citrus category)
• Orange : Squash (orange can be processed into a squash/juice)
• Tomato : Puree (tomato can be processed into puree)

Concept / Approach:
Decide whether the second term is a processed product of the first (product relation) or a class label that subsumes the first (category relation). Three pairs are clearly “produce → processed product.” One pair is “member → class.”

Step-by-Step Solution:
Apple : Jam → product relation.Orange : Squash → product relation.Tomato : Puree → product relation.Lemon : Citrus → taxonomic (hyponym → hypernym) → odd one out.

Verification / Alternative check:
Flip each pair: “Jam : Apple,” “Squash : Orange,” “Puree : Tomato” are still meaningful as product → source, while “Citrus : Lemon” becomes class → member, not a process/product inversion. The relational asymmetry confirms the category case is different from the product cases.

Why Other Options Are Wrong:

• Apple : Jam → processed product.
• Orange : Squash → processed product.
• Tomato : Puree → processed product.
• None of these → there is a single category relation (Lemon : Citrus).

Common Pitfalls:
Over-focusing on the food domain and missing relation types. Always identify whether the second term is a product, a place, a tool, or a class label.

Final Answer:
Lemon : Citrus
