A) String
B) Boolean
C) Integer
D) Array

Answer 1

The value of the "id" key is an Integer, indicated by the numeric value 12345 without quotations, which signifies that it is not a string, boolean, or array.

Step-by-step explanation:

In the provided REST API example, the value of the "id" key is 12345. The correct answer to what type of value this represents is C) Integer. An integer is a whole number without a fractional component and is typically used in programming to represent numeric data. In the context of JSON (JavaScript Object Notation) which is often used in REST APIs, integers are one of the several types of values that can be represented. In this example, a numeric value without quotes denotes an integer, while strings are encapsulated in quotations.
