A network team is designing a REST API that will be consumed by multiple clients written in different languages. The API must support complex nested data structures and be validated against a schema. The team is considering JSON and XML. Which factor most strongly favors JSON over XML in this scenario?

JSON provides built-in schema validation standards.

JSON has native support for arrays and booleans, which map directly to data types in most programming languages.

JSON supports namespaces to avoid element name conflicts.

JSON allows comments for documentation within the payload.

Which characteristic is unique to JSON compared to XML?

It uses tags to define elements.

It supports attributes on elements.

It uses key-value pairs and arrays.
