Answer 2

The correct option is Option D - All of these.

#define, #ifdef, #endif all of these are C preprocessor.

The C compiler automatically uses the C preprocessor, a macro processor, to modify your programme before real compilation. Because it enables you to define macros, which are condensed versions of lengthier structures, it is known as a macro processor.

One of the often used directives in C is #ifdef. Conditional compilations are supported. Before we include any additional code, the preprocessor is meant to check to see whether any specified macros already exist during the compilation process.

The #endif directive in the C programming language is used to define the directives #if, #ifdef, and #ifndef. When a programme comes across the #endif directive, it checks to see if the preprocessing of #if, #ifdef, or #ifndef was successful.

An identifier or parameterized identifier is associated with a token string by using the #define command to build a macro.
