Preprocessor Commands in C++: Note the code and preprocessor instructions in order to answer each question.

What will the following code do?

#define plus + int main() { cout << (3 plus 5) << endl; }

A. The program will compile, but immediately crash.

B.	The program will not compile because C++ expects there to be an operator between 3 and 5, not a variable name.

C.	The program will not compile because 'plus' is not a declared variable.

D.	The program will compile and print '8'.
