Option B is the correct syntax to overload the [] operator function as a member function of a class for constant arrays. The const keyword after the function declaration ensures that the function does not modify the object on which it is called, making it safe to use with constant objects. Options A, C, and D are incorrect syntaxes that do not properly overload the [] operator function.
