What is the meaning of 'accessory'?

• A. a person that helps another person commit a crime
• B. an object that is added to another in order to make it more useful or attractive
• C. a decorative item added to a garment
• D. a device used to store data

Answer: (B)

The main idea being tested is how the word accessory is used to describe something added to another item to improve its usefulness or appearance. In everyday English, an accessory is an extra item that accompanies a main object to enhance it—like a belt or scarf with clothing, or a decorative piece that accompanies a garment or device. This broad sense fits best with the definition that describes an object added to another to make it more useful or attractive. There are specialized uses in other contexts, such as legal language where accessory can refer to someone who helps another commit a crime, but the common meaning here is the idea of a supplementary item that enhances something.
