Best Answer Explained in Below-:

In the C programming language, basic data types refer to the fundamental types that can be used to define variables. The most commonly recognized basic data types are `char`, `int`, `float`, and `double`. Each of these types represents a specific kind of data: `char` is used for single characters, `int` represents integer values, `float` and `double` are used for floating-point numbers, with `double` offering higher precision.

The option `void`, however, is not a basic data type in the same sense. Instead, `void` is a type that indicates the absence of data. It is primarily used in function declarations to specify that a function does not return a value. For example, a function declared as `void myFunction()` does not return any data to the calling function.

While `void` plays a crucial role in function definitions and pointers, it does not store data itself, distinguishing it from the core data types. Therefore, in the question of which option is **not** a basic data type, the correct answer is `C) void`.
