Consider the following C++ programint a (int m){ return ++m; }int b(int&m){ return ++m;}intc(char &m){ return ++m; }void: main () {int p = 0, q = 0, r = 0;p + = a(b(p));qt = b(a(q));r+ = a(c(r));cout<< p <<< I;}Assuming the required header files are already included, the above program

• A. results in compilation error
• B. print 123
• C. print 111
• D. print 322
