Which types of data are considered primitive in C language?

In the C programming language, primitive data types are the basic building blocks for data manipulation. They are predefined by the language and represent single values, which can be used directly to perform operations.

The correct choice includes int, char, float, and double, which are the fundamental data types in C. An 'int' typically represents integers, 'char' is used for single characters, 'float' represents single-precision floating-point numbers, and 'double' is used for double-precision floating-point numbers.

These primitive types allow programmers to store and manipulate values directly, perform arithmetic operations, and create more complex data structures. They form the foundation for all other data types in C, including derived types like arrays and structures, which are built from these primitive types.
