Choose the odd pair of words:

The correct answer is D. In the first three pairs, the craftsperson is linked to the instrument he works with: a blacksmith uses an anvil, a carpenter uses a saw, and a barber uses scissors. Each pair follows the same relation of worker to tool.

Goldsmith: Ornaments breaks that pattern. Ornaments are what a goldsmith makes, the finished product, not an instrument he uses. The matching relation would be something like goldsmith and hammer or goldsmith and crucible.

• A (Blacksmith: Anvil): The anvil is the iron block on which hot metal is shaped. It is the blacksmith's basic tool.
• B (Carpenter: Saw): The saw is a cutting tool used in woodwork.
• C (Barber: Scissor): Scissors are the barber's cutting instrument.

The core concept is the analogy of function, where the first word is a person and the second is linked by use. Such questions test reasoning skills under CSAT and often appear in UPPSC and other state exams. A Mains angle is the study of traditional artisan communities and their skill-based livelihoods.

Trap: Many aspirants pick Blacksmith: Anvil because the anvil is heavy and not handheld, and so they treat it as the odd one. Focus on the relation, not the size or portability of the object.
