Which of the following is a guideline for overloading operators in C++?

Overload as many operators as possible to ensure full coverage
Only overload operators where it enhances readability and usability of the class
Prefer global overloading to member function overloading for arithmetic operators
Always return objects by value to ensure encapsulation

The correct answer is: Only overload operators where it enhances readability and usability of the class

The guideline for overloading operators in C++ is to only overload operators where it enhances readability and usability of the class. Option B is the correct answer because overloading too many operators can make code confusing and difficult to understand. Option A may lead to unnecessary overloading and bloated code. Option C is incorrect because member function overloading should be preferred over global overloading for arithmetic operators for better encapsulation. Option D is also incorrect because returning objects by value may lead to shallow copies and potential issues with encapsulation. Therefore, B is the best guideline for overloading operators in C++.
