Explanation by: Admin

The compilation of a C program goes through several stages:

Preprocessing:

  • The preprocessor handles directives like #include, #define, and #ifdef.
  • It replaces macros, expands header files, and processes conditional compilation.

Compilation:

  • Converts the preprocessed C code into assembly language.

Assembly:

  • Translates the assembly code into machine code (object file).

Linking:

  • Combines multiple object files and libraries into a single executable.

Since preprocessing is the first stage in this sequence, the correct answer is (C) Preprocessing.
