Odd-one-out (verbal classification): Choose the word that does not belong to the group. Items to analyze by usage/category (upper-body vs. lower-body garments; outerwear vs. innerwear): Coat, Shirt, Blouse, Trousers Choose the single word that is different from the rest.

Given data

• Coat, Shirt, Blouse, Trousers

Concept/Approach
Classify by the part of the body typically covered.

Step-by-step reasoning
Coat → upper-body outerwear. Shirt → upper-body garment. Blouse → upper-body garment. Trousers → lower-body garment.

Common pitfalls
Grouping by formality instead of the body part covered leads to ambiguity; the anatomical category gives a unique outlier.

Final Answer
Trousers
