Which data modeling language returns data in the form of an object that contains key-value pairs?

• A. Xml
• B. Aci
• C. Json
• D. Rest

Answer: (C)

Data is often represented as an object with named properties, so a format that uses an actual object built from key-value pairs fits this idea perfectly. JSON does exactly that: data is shown as an object enclosed in braces, with entries like "name": "Alice" and "age": 30. This structure maps directly to common programming constructs such as objects, dictionaries, or maps, making data easy to access by key and simple to serialize and deserialize across systems. XML, while capable of encoding the same information, uses nested elements and attributes rather than a straightforward key-value object. REST is not a data format at all but an API design approach, and ACI isn’t a standard data modeling language for returning data as a key-value object. So JSON is the best fit for the described pattern.
