Refer to the exhibit. What does apple represent within the JSON data?

An array is an ordered collection of values, denoted by square brackets `[]`, not a single word like 'apple' by itself.

An object is an unordered collection of key-value pairs, denoted by curly braces `{}`, and 'apple' is not a key-value pair or an entire object.

A number in JSON represents numeric values (integers or floating-point) without quotes, whereas 'apple' is clearly text.

In JSON, 'apple' enclosed in double quotes (e.g., `"apple"`) is explicitly defined as a string data type. Strings are used to represent text values.
