Answer: Option A.
In C++, stream insertion operator << is used for output and stream extraction operator >> is used for input.
Cout is an object of ostream class which is a compiler defined class. When we do cout<<obj where obj is an object of our class, the compiler first looks for an operator function in ostream, then it looks for a global function. One way to overload insertion operator is to modify ostream class.
