Final answer:
The correct answer is C) >>, <<, where the >> operator follows the cin object for input, and the << operator follows the cout object for output in C++.
Step-by-step explanation:
The operator that always follows the cin object is the >> operator, and the operator that follows the cout object is the << operator. Therefore, the correct answer is C) >>, <<. These operators are used for input and output operations in C++ programming. The cin>> is used to extract data from the user, and the cout<< is used to insert data to be displayed to the user.
