Which of the following is a characteristic of operator overloading in C++?

Operator overloading in C++ allows existing operators to have new meanings when used with user-defined types. This means that instead of being limited to the predefined behavior of operators, they can be customized to work with user-defined data types. This improves the flexibility and usability of the language. The other options are incorrect because A is incorrect as operator overloading does not change operator precedence. C is incorrect because it does not remove standard operators, instead it extends their functionality. D is also incorrect because operator overloading can be applied to any type of operator, not just mathematical ones.
