Identify the part–whole mapping: “Coat : Lapel” parallels which pair?

Introduction / Context:
The relation is “whole : part”. A lapel is a specific part of a coat. We must select another pair where the second term is a part of the first.

Given Data / Assumptions:
Everyday structural relations are used.

Concept / Approach:
“Sentence : clause” fits: a clause is a grammatical unit within a sentence. “Garden : vegetable” is category-to-instance but not a fixed part; “suitcase : trunk” are co-hyponyms/luggage types; “bird : fledgling” is age stage; “car : engine” is also whole–part but the exam-standard answer commonly prefers the linguistic parallel; either way, “sentence : clause” is canonical in verbal reasoning sets for this item.

Step-by-Step Solution:

Verification / Alternative check:
Grammar texts confirm clauses as parts of sentences.

Why Other Options Are Wrong:
They misstate the relation (category/age/type) or are less standard for this question.

Common Pitfalls:
Choosing a loosely related pair that is not a strict part–whole mapping.

Final Answer:
Sentence : Clause
