Which of the following is NOT a basic data type in C?

• A. int
• B. float
• C. char
• D. string

Answer: (D)

The reason "string" is not considered a basic data type in C is that C does not have a built-in string data type like some other programming languages. Instead, strings in C are represented as arrays of characters, ending with a null terminator (`'\0'`). This means that, while you can work with strings in C, you do so using the `char` data type and handle character arrays to create and manage strings. In contrast, `int`, `float`, and `char` are all fundamental data types in C. An `int` is used for integers, a `float` for floating-point numbers (decimals), and a `char` for single characters. Understanding the nature of these basic data types is crucial for managing data in C programs, whereas strings require additional considerations, such as memory management and manipulation functions, which are not necessary for the simpler data types.
