Which word means 'a product or good that can be bought and sold'?

• A. Commodity
• B. Code
• C. Coherence
• D. Commission

Answer: (A)

The main idea is recognizing a term for goods that are bought and sold in markets. A commodity is a basic good that is traded widely and standardized so one unit is interchangeable with another, like oil, wheat, or copper. This interchangeable, market-tradable nature is what makes it the best fit for “a product or good that can be bought and sold.” In contrast, a code is a system of symbols for communication, coherence means logical consistency, and commission can refer to a fee paid to an agent or the act of ordering something, not the product itself.
