Option C is the correct syntax to declare the operator function operator[] as a member function for non-constant arrays. The "&" after the return type indicates that the function returns a reference to the object, allowing it to be modified. Option A is incorrect because it lacks the "&" needed to return the array by reference. Option B is incorrect because it returns a copy of the requested element instead of a reference. Option D is just syntax with no operator overload.
