Why each option
In a JSON schema, "R20" would typically represent a value associated with a key, completing a key-value pair.
In JSON, data is represented as key-value pairs. If "R20" is part of a JSON structure like `"someKey": "R20"`, then "R20" is the specific piece of data assigned to `someKey`, making it a value. Values can be strings, numbers, booleans, objects, arrays, or null.
An array is an ordered list of values, enclosed in square brackets `[]`, not a single string like "R20".
An object is an unordered set of key-value pairs, enclosed in curly braces `{}`, not a single string like "R20".
A key (or "name") in JSON is a string that uniquely identifies a value within an object, usually enclosed in double quotes and followed by a colon, e.g., `"myKey":`.
