Why is operator= limited to being a member function?

To prevent redefining the built-in assignment behavior
Because it only operates on two objects of the same class
To simplify syntax
For performance reasons

The correct answer is: To prevent redefining the built-in assignment behavior

Operator= is limited to being a member function because it allows the developer to define a customized assignment behavior for objects of a particular class. This prevents the built-in assignment behavior from being accidentally changed or redefined, ensuring consistency across different parts of the program and avoiding potential errors. Option B is incorrect because operator= can be overloaded to work on objects of different classes as well. Option C is incorrect because making operator= a non-member function would not simplify syntax, but rather make it more complex. As for option D, while performance can be a consideration for making operator= a member function, it is not the main reason for this limitation.
